I'll start with fellow followers of Christ and say a lot of the ones I've met aren't as easygoing as would be stereotypical. Now you might read the Bible (or the Book of Mormon, or the Book of Hagoth; I have 'em all) and think "hey that person over there is famous for their devotion, I'm going to strike a friendship" and then realize it's a lot closer to "stepping on eggshells" than you might think. Points to other Hagothists/Mormons though as they actually have been understanding people. Gossip, hate, whatever you want to call it, I'm no stranger to bearing witness to it, and you often wonder "wait, why are they involved in this". It's also complicated because, by the same token, they have positives like what we might call tolerance towards the LGBT, so there are other dimensions to it.

Technically not a "religion" per se, but the atheist situation strikes me as odd. It often seems like their attitude towards adherence to God is second-hand because what they'll say about God they'll never say about government, or they'll do it rarely. Everything to most of them considered "questionable" or "concerning" is only "questionable" or "concerning" when it involves divine authority. I have joked before that if climate change or Marxism was in the Bible, nobody would believe them.

I also noticed a lot of Buddhists couldn't quote sutras from the Tripitaka or don't follow them to an extent where the individuals are Buddhist-esque enough to rely on to be peaceful towards your dilemmas, almost as if it's for show. Heck, I'm not a Buddhist yet can quote sutras that aren't in the Tripitaka (because not all of them made into the final edition).
