What sort of post or comment gets you downvoted the most? Especially if you don't think it's bad behavior in the first place, or don't care. Does not have to be on Lemmy, but we are here...
One of the good things about Lemmy IMO is that it's small enough to see the posts that are unpopular. If you do "Top Day" on most channels, you cash reach the bottom, see what people here don't like.
As far as comments, attempting to rebut the person who is telling me my post sucks, is what gets me into negative numbers most often. The OP is going to voite it down, of course, and nobody else cares, usually.
Anytime I mention something vaguely positive about religion. I'm a former religious studies scholar who studied comparative religions. I have two degrees in the subject. I don't think I'm saying anything controversial: the main thing I usually write is that you cannot usually say that a religion is a monolith - they are pretty complex phenomenon with many variations within them. You can say that Salafis are the totality of Islam. You can't say that evangelicals are the totality of Christianity. You can't say 969 in Burma is the totality of Buddhism. You can't say Hindutva is Hinduism. You can't say that the Settlers on the West Bank are the totality of Judaism. Religions without any variation or complexity usually die after a generation or two. I don't just have these arguments online, I am used to have them with students and with friends. But nuance has few safe harbors on the internet....
I've simply said that while I don't consider myself particularly religious, I enjoy my church because of the wonderful friendships, the genuinely welcoming environment to all, and the sense of community it brings me, and all the boring atheists come out of the woodwork to herp at me. Like what do you care that I enjoy something? I'm not inviting you.
