You're a bad troll, but I'll give a thoughtful reply anyway.

There is something wrong with believing in religion when your religion's holy book explicitly says to murder non-believers. The difference between extremist Muslims and moderate Muslims is that extremist Muslims actually do what the Quran encourages them to.

The entire book may not revolve around this idea, but it is mentioned in many instances. Pretending ISIS's hatred of other religions, women, gays, etc. is some sick perversion of Islam, rather than a direct result of Islamic doctrine, is bogus. Moderate Muslims can choose to ignore Islam's calls to violent action, but I'd argue that the moderates are the ones perverting Islam by inserting secular morality. ISIS is simply following the Quran by each and every word.

On the note of atheism, it's not even close to a religion. How many people would be willing to lay down their lives or murder in the name of the Milky Way? All religions are a problem, but there's no denying that Islam is the biggest problem. One bad apple does not ruin the whole tree, but when you start seeing dozens of them pop up then it's about time to cut the entire tree down.

As a non-religious white person who has been sitting around while white people are essentially blamed for every single bad thing that has ever happened in history, up to hundreds of years before today, I think it's awful that the moment anyone even opens their mouth to criticize Islam, they are shamed. The fear of being wrongly labeled a xenophobe or racist really has a way of destroying the intellectual discourse that is needed to create progress in human civilization. It's time for Islam to behave like a species that has walked on the ****ing moon.
