honestly, anytime someone is wearing a cross or mentions they are Christian or religious, I assume they are unsafe and likely have some kind of bigoted views. To be fair, I think most people are bigoted to some extent, we can hardly escape the acculturation that comes from growing up and living in a society that has heteronormativity baked into it.
I know for sure that not all Christians or religious folks are anti-LGBT+, but where I live it's fairly predictive that if someone is religious they're also more likely to be conservative and have reactionary views on topics like science (e.g. more likely to be creationists, anti-vaxxers, etc.), gay rights, trans rights, etc.
