"There is no Aryan equivalent in Islam" What about Muslim? Fitting well IMO. Muslims at the top, all others under the heel, summit or/and die.

"Funnily enough, even ISIS brags about how racially tolerant it is in its propaganda." Yeap and Nazi made beautiful movie about how the Jews were happy in their new settlements. They even had an orchestra... So Isis doesn't kill Christians and Jews... Nice to hear it.

"Discriminating based on religion isn't the same thing as discriminating based on race." This needs a little of explanation. Yes, you can convert. But it is the same principals. One above the others, and kill/oppress the others. I can't see any difference.

"Islamophobic defense mechanism" And this the typical Muslim Fanatic extremist defense when cornered. See, I can do it as well.
Then you have to tell me what is wrong to fear a religion, or to hate a religion? Religion are concepts, so I can hate or fear racism (you mixes with xenophobia), freedom, democracy, dictatorship etc. Why religions should be exempted? To be fair, yes I do hate the lack of democracy, the open discrimination, gender inequality, food prohibition, mind control, promotion of violence, promotion of slavery, call to murders, oppression of others recommended in holly books. Christianity and Jewish faith have been tamed by the Enlightenment and hundred years of Religious wars.
So it is perhaps time for Muslim Scholars to recognise (and some do exactly this) it. And it is time to educate the Muslim faithfuls of what is really the Koran, and to put a stop on legends.
As soon as the Imam will tell hat the Koran was not written directly but years after "God" dictated to the prophet, that as the Christians for the New Testament, the scholars choose what should be in it, that later, new scholars decide what was Islamic or not. Then we will start to make progress.
But of course the Muslim Clergy in majority doesn't want this. First of all, because themselves don't know it. And the ones who know don't want to loose power in the masses.
