I arrived here not by running or as a reaction to being treated poorly, the poor treatment was a result of my already being an atheist.
I think the most uncomfortable thing for a lot of christians is that many atheists became that way by reading the Bible, that is what it was for me.
If you are ever curious what the bible looks like to an atheist, I highly recommend the book God is Disappointed In You.
I'm not going to hassle you either because all you had to say for your religion was calls to kindness. My biggest complaint about the christianity I usually encounter is that it is primarily about subservience and never passing along any of Jesus teachings about kindness or forgiveness or any other common human decency.
I think you are honestly curious and you seem to have understood my point about how you see a tainted perspective of atheism because you are always bringing your Christianity into each conversation about atheism you are in. Being an atheist is different than being not a Christian or not religious. I'm not sure how to explain it from 0 but I'm happy to try to answer questions about atheism when Christians aren't around or being addressed.
I'll even share my favorite meme on the subject.
