I reread the entire thread again and I haven't found a single post where atheists are denigrated. Possibly there was one quote about the enemy's plan for your life. That may have been slightly on edge.
The quote about one lost sheep didn't sound offensive to me at all. I absolutely didn't think about atheists when reading it and I don't think it was meant to threaten or denigrate anyone here. That's why I absolutely didn't see a reason for offence. And I am very sensitive to threats and judgement. However in the whole thread I didn't see anything offensive. I truly wonder which quote are you talking about.

What is true and I agree with you Gus is that AFTER your critical remark, a couple more posts came which may sound like a provocation.

I needed a place to talk about spirituality because it's a huge part of my trauma but I have absolutely no one and no where to talk about it. Neither in real life nor online, not even my therapist understands me. But that has little to do with this forum, that's just my venting . I think I was so triggered by this misunderstanding because it just reassured me that all forums are the same and I will never find help with my own problems.
