As a Christian who doesn’t follow much of the super religious “rules”, I think it’s kind of a red flag but sometimes it’s not. Red flag because my girlfriend’s ex-friend was super devout and put it all over her bio and was very ableist and homophobic. My friend, for example, is agnostic, so he’s not sure if spirituality exists. He has a friend who’s super devout and constantly talks about Christianity. She has a Discord server about Christianity and most of her friends are Christian who just talk about Jesus and God all the time. She puts the crosses and bible verses in her bio too. She’s very nice and tries to be accepting but seems kinda judgmental or like “Oh, your non-traditional ways are… nice I guess.”
She constantly asks my friend how his relationship with God is and if he reads the Bible and what his favorite verses are, even when he says he’s not super religious.
My mom as of recent has become super religious, and while she is pretty left-leaning, thinks the only way to believe is to be Christian and you HAVE to believe in Jesus or you’ll die instead of live forever in Heaven.
I don’t care if people keeps their religions to themselves. Actually, some of those people are/were very nice to me even when they knew I was an atheist.
But the sad part is, the majority of the religious people behave like mujahedeen in Türkiye, and the current administration supports and pushes this behavior.
I try to stay away from those tools, but some of them are in my extended family and I can’t cut them of for financial and emotional reasons. At least they don’t bother me with it.
