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 enjoy theology and discuss it somewhat regularly with my wife who also is an ex catholic non Christian that likes discussing catholic theology. To me it’s like philosophy but more aspirational, distant, and constrained. It also provides a framework to process religious trauma, express frustration with bad Christians, and to process our feelings as people oppressed by Christiandom.
I say this to provide context, so that when I say I can’t fucking stand those people it’s not that I’m not comfortable hearing about religion or that I just hate it. I actually quite love it, and part of me is sad that who I am and my religion (paganism) block me from having more access to it. But Christians who are like that are rarely tolerant of things like religious differences (I sometimes got called a devil worshipper by protestants for being catholic growing up), lifestyle differences, and people who aren’t like that.
I also find that they are often religiously incurious. They find the solution that works for them, and stick with it, which I can’t judge, but when they study it they don’t ask about why other Christians think differently, they don’t apply the rigor that Jews and Catholics cherish, and they rarely bother learning about other religions either.
But then we get to the primary issue I have, I’m not Christian, and Christianity is regularly used as a tool to oppress me. I’m not interested in returning to it, and I’m frustrated at how much cultural and political power it has in my society.
