Which religion is founded on the most provable facts?

This is going to be pretty unpopular to some of you, but, there appears to be as much factual basis beneath Qanon as there is beneath most of the religions I’ve ever heard of.

Every other language is a ‘foreign language’ to you. We’re used to Christianity so when someone talks about some of the tenets of other foreign religions, they sound crazy. That’s because they are.

What’s the rule for being safe in mocking fantastic beliefs? Do they have to be really old to be protected? If I wait two thousand years, am I not allowed to call Qanon believers “batshit crazy?”
