Dude are you serious? The whole point of why the Pythons made Life of Brian is because they rejected the notion that religion is a taboo subject for comedy. And as the movie shows, there are many things about organized religion that deserve mockery and sometimes scorn.
Wouldn't the world be a better place if we could mock things that people hold sacred? Like Islam? Granted, you could get your chopped off for poking fun at Mohammed the Prophet, but it's frustrating that Muslims are afforded this special privilege and Christians not. Or better yet, how about transgender people? The lunatic liberals tell us that troons don't deserve to be mocked and made fun off because they're 'stunning and brave.' But recent events have shown us that many troons are a bunch of mentally ill psychopaths who'd happily cheer the deaths of us normies if given the chance. If that's not a prime source for comedy I don't know what is.
