Sounds like the Christian nazis in action.
To call Nazis Christians of some form, or influenced by Christian teaching in any way is either deliberately evil or the highest form of stupidity.
To reference the Crusades or some other battles where Christianity played a role back in medieval times in order to try to make the case Christianity is just as murderous and wrong as what modern Islamists are doing is void of rationality and absurd. One cannot judge how a more barbaric culture dealt with its affairs 500 or 1000 years ago by today's more civilized and educated standards.
To try to distance what Islamic movements have done to their non-Islamic neighbors over the past 100 years --- attack, murder, blow up, hate, spread lies, and be utterly intolerant – from the religion of Islam is just plain stupid or totally
Here is my opinion and my beliefs ---
God is real. So is the devil. The basic dogmas and tenets of Islam is not the fullness of truth and there is something malevolent within which causes many of its adherents to take its teachings to a fanatical, intolerant, hateful extreme. This violent, hateful fringe is so large and prevalent it cannot be from God. They are demonic in their ways and in their delight in murdering innocents.
Christianity is made up of sinners, and so it is not perfect. But its teachings are the fullness of truth revealed by God and Jesus Christ God. Its sins are there, but its goodness throughout history is a thousand times more powerful. Christianity has civilized a barbaric world and saved this world from itself. For anyone to even suggest there is anything all that similar between the historical works and truths of Christianity and that of Islam is evil or dishonest or that of someone not of sound mind.
