While I don't think people should do things to antagonize other people pointlessly(not just religions), the fact people are rioting about a book being burned is beyond moronic.
That's exactly the point they are making in burning it. sacred to you is not sacred to me. Thinking that they have any right to enforce their religious beliefs on anyone else is not okay, doing so violently reveals they are the villains.
If Islam wants to be part of modern society, they need to accept others are not religious, and some are vehemently against religion, and that those views, demonstrated in public, is their right too.
The core issue a lot of people have with Islam in particular is the belief that they must enforce Islamic law on others around them.
Asking your beliefs be respected is not enforcing anything on to anyone else, and deliberately baiting an oppressed group for a reaction by going out of your way to disrespect them, and then pulling a surprised Pikachu face when they react is antagonistic fascist bullshit.
