You might perhaps know what the Chinese expression 是口非心 means. If there are Muslim people not behaving properly in a Western nation, then put them in their place - not because they are Muslims but because of their improper behaviour as individuals. Farting in a mosque is as improper as farting in a church or a Buddhist temple. It offends other people and is considered to disturb the "holiness" of the place. While the death penalty for this may be out of proportion in Western eyes, you will need to realise that this is a Western view not necessarily shared by other non-Western people, whether you like it or not.

There are so many contradictions in this world. With reference to your buddy on here, one of them is the hypocrite who blows the trumpet for tolerance towards gays, lesbians and women but constantly sows anti-.Muslim sentiments and is arguing about Africans being unable to speak and write proper English. 是口非心. Indeed.
