@warandpeas I think many Christians feel this way. I do. I'm still "in the church" but I don't feel any affinity with people who are preaching hatred.
Jesus said "love your enemies and pray for those who persecute you." So if we think someone is going to hell, how is it loving or kind to put that on a sign instead of having a real, human conversation?
If I were going to hell, I'd want someone who loved me to talk to me about it gently and respectfully.
