Islam nowadays are religions most used to justify violence and prohibitions against freedom of opinion. When people embrace violent approach, either by doing it or kowtowing to violence, they use Islam as justification. I don’t see people beating up someone for having a different opinions and do it under the name of Buddha, for example.
Religions are undoubtedly a highly effective (and defective) euphemistic techniques politicians use to guide the population. It’s not wise to say that I like bigger tax because I am lazy. I would rather say that I prefer that for more agreeable reasons, like social justice.
