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. I purposely avoid anyone like that - and honestly, nobody where I’m from would be like that anyway as religion is a personal experience here and not one that is overtly “spread” or talked about openly. We aren’t big fans of cults/religions unlike the US (which seems to get right into that thing), and generally see the mess they, or more importantly, their followers cause around the world and at home. Even our religious schools use religion very marginally as they’re aware most of the parents are only sending their kids there because the fees aren’t huge and the quality of education is a bit better than the public system.
