So let's put what you are advocating into a slightly different context.
According to the standard that you are applying to all Muslims 100% of all white Americans alive today must be held accountable for the atrocities that occurred during the hundreds of years of slavery in this nation. They must also be held accountable for the genocide of the native American Indians too. All of the rapes, murders, torture, slaughter of women and children must be held against them simply because of being an American today.
According to you there is no way to "get past" the violent history of the USA no matter "however nice or patriotic any given" American might be.
Does that put this into perspective for you?
Yes, that helps me understand your objection but the supposition is false. The violent history of the past and the religious basis for those atrocities has been universally condemned and discredited by Americans in the present. There is no atrocities related to slavery or against native Americans sanctioned by the people alive today whereas In Islam such atrocities are not only being committed on a daily basis against the innocent, the official fundamental teaching based on the Koran to maim and kill is encouraged.
Lets say I was born and raised in the Catholic church. If at some point in my life I became aware of the atrocities of the past and realized they were based on teachings derived from scripture that is still being taught and encouraged to this day I would face a moral dilemma to either remain Catholic or rise out of that grave and become something else.
If I continued to remain Catholic wouldn't I be making a deliberate choice to disregard that knowledge and support the teachings that I know have been responsible for evil in the past, evil occurring to this day, and evil bound to happen in the future if such teaching is not extirpated by people of higher intelligence and integrity?
If you read the Koran it does sanction a barbaric method of controlling the population based on an extremely perverse view of human sexuality and life on earth.
How can you not see that there is no way to identify oneself as a Muslim without sharing the guilt of all the evil done in the name of Islam based on teaching that is actually there in the Koran that you can read for yourself that is derived from the teachings of a known pedophile, a violent megalomaniac, having auditory and visual hallucinations??
