Which translation are you using because I haven't seen any that made the additions and changed the meaning as you did.
I rely mostly on the translations of A.J. Arberry, Maulana Muhammad Ali, and Mohammed Marmaduke Pickthall, which are by and large the most accurate and literal. If you truly cared about accuracy in translation, you'd lambast your friend Fitnuts for using one of the most egregiously warped translations in print.
Why are you avoiding the part that says to slay those who left Allah? It was unambiguous too.
Don't be thick. I haven't avoided anything.
Why should you, then, be two parties in relation to the hypocrites (munafiquun) while Allah has made them return for what they have earned? Do you desire to guide him whom Allah leaves in error? And whomsoever Allah leaves in error thou canst not find a way for him. They long that you should disbelieve as they have disbelieved so that you might be on the same level; so take not from among them friends until they flee in Allah’s way. Then if they turn back, seize them and kill them wherever you find them, and take no friend nor helper from among them, except those who join a people between whom and you there is an alliance, or who come to you, their hearts shrinking from fighting you or fighting their own people. And if Allah had pleased, He would have given them power over you, so that they would have fought you. So if they withdraw from you and fight you not and offer you peace, then Allah allows you no way against them. You will find others who desire to be secure from you and secure from their own people. Whenever they are made to return to hostility, they are plunged into it. So if they withdraw not from you, nor offer you peace and restrain their hands, then seize them and kill them wherever you find them. And against these We have given you a clear authority. - 4:88-91
A
munafiq is a person whose actions are different from his or her intentions. In a Qur'anic context, it refers to a person who claims to be a Muslim and practices Islam publicly while privately detesting it. The passage goes on to expressly forbid killing those who are tired of fighting ("who come to you, their hearts shrinking from fighting you"); those who are members of an allied party ("those who join a people between whom and you there is an alliance"); and those who desire peace and an end to the conflict ("if they withdraw from you and fight you not and offer you peace, then Allah allows you no way against them.") This is repeated so that slaying non-combatants is clearly forbidden.
So are you denouncing the life and sayings of Mohammed then?
You won't be able to find any sahih hadith demanding the humiliation and terrorizing of the ahl al-dhimma. If you were as familiar with Islamic juristic history as you seem to think you are, you'd know that most of the demands for "humiliation" came from medieval commentators and a few jurists from the same period. Earlier scholars and jurists, such as
Abu Yusuf, held opposite views:
"No-one of the people of dhimma should be beaten in order to exact payment of the jizya, nor made to stand in the hot sun, nor should hateful things inflicted upon their bodies, or anything of that sort.. Rather they should be treated with leniency."
Are you a Muslim that denies Mohammed's life and sayings? Or do you agree Muslims are to follow the life of Mohammed? And if so, what is the oldest, most respected book describing his life?
The oldest and most respected book is the Qur'an, which contains a multitude of references to events in Muhammad's life. It is the only account that can be considered 100% factual and reliable in Islam, and the only source of guidance that all Muslims share in common.
Next in supposed reliability for many Muslims are the hadith collections. The Sunni canon consists of Sahih Bukhari, Sahih Muslim, Sunan Abu Dawud, Sunan al-Tirmidhi, Sunan as-Sughra, and Sunan ibn Maja. Shi'ites generally reject the Sunni canon, and acceptance of other collections among Shi'ites tends to vary from sect to sect. The most prominent sect, the Twelvers, accepts the Kitab al-Kafi, Man la yahduruhu al-Faqih, Tahdhib al-Ahkam, and Al-Istibsar. Even Muslims who believe in one canon of ahadith or another admit that they're non-divine and fallible. After all, in spite of the careful research completed by most compilers, ahadith are based on oral traditions transmitted over multiple centuries and must be tested for accuracy using the Qur'an. As Bernard Lewis wrote, "the collection and scrutiny of Hadiths didn't take place until several generations [after Muhammad's death]... during that period the opportunities and motives for falsification were almost unlimited."
The biographies are even less reliable. Unlike ahadiths, biographical accounts were based on oral traditions with unknown isnad (chains of transmitters). Because the transmitters of these traditions are not even known, the reliability of these biographies is even more questionable than the reliability of hadith collections and no definitive conclusions should be drawn about the life of Muhammad (SAW) based on biographies alone.
The caravans belonged to those who oppressed and tortured Muslims, making them legitimate targets.
and the Qurayza who were neutural and according to Muslim sources, 600 to 900 were beheaded because they would not convert.
The B. Qurazya were not neutral according to any account. The traditional story runs thus. They were a Jewish tribe living in Madinah while Muhammad (SAW) and his followers were also there. In 627, Madinah was besieged by the Makkan Quraysh. The Makkans outnumbered the Muslim-Jewish defense, and the B. Qurayza presumably betrayed their allies for the Quraysh because they thought that they would be defeated. As it turned out, their betrayal was apprehended and they were unable to successfully attack their former allies. After the Muslim-Jewish victory, the B. Qurayza were accused of treason and surrendered on the condition that they would be allowed to select their arbitrator from among the Muslims. They chose Sa'd ibn Mua'dh (or he was appointed), who chose execution as a punishment for their betrayal. The treasonists were summarily killed.
Of course, the reliability of this account is questionable. No archaeological evidence exists of the execution and it was found that the traditional account was based on a story transmitted by Madinan Jews.
Traditional Islam or the new and improved Islam? The one being pushed to gain acceptance into the European Union?
Scriptural Islam.
"Legitimate" traditions. So you pick and choose what you want to believe and throw out the rest.
I accept ahadith that don't contradict known facts or the Qur'an.
Do you denounce all the Islamic judgments then, of apostates?
Noting that the Qur'an forbids slaying purely on the basis of belief, it seems clear that any hadith or tradition demanding that would be illegitimate.
Oh I understood it, especially the part where it talked about how accepted his accounts were. Something you seem to want to contradict.
I'd estimate that most Muslims don't make it through an entire hadith collection in their life, much less a 9th-century biography. Your arguments rely on the fundamentally unreliable accounts of Ibn Ishaq/Ibn Hisham being a "holy book"

lol

because you're unable to put forth a legitimate criticism of Islam based on what is said in the Qur'an.
Or you could just google "Sacred Hadiths" and see what you get (over 3,250,000)
"Sacred Shit" yielded 1,530,000 results. What conclusions should I draw from this?
Sirat Rasul Allah is not a hadith collection.
Now isn't that odd...because many sites even seem to suggest that the word Sharia and Sira are related. Do you denounce Sharia law, Kalam? I wonder how many real Muslims do.
I accept what has been laid down in the Qur'an and (in some cases) explained further by authentic ahadith. I do not feel inclined to automatically accept any "ruling" issued by a person other than Muhammad (SAW) or base my beliefs on what the jurists of one school or another deem proper.
