Generally I humorously berate them for their immoral beliefs citing all the murder, rape, baby killing and slavery their god is into. They seem to know next to nothing about what is written in their book. You'd think you'd at least read a book you're going to base your life on.

I once said I’d become a Nazi and said I was going to loads of meetings and Nazis are such good people etc. They freaked out at me and cited all the things the Nazis believed and did as being evil. I used all the arguments they used to defend their evil religion. You’re taking it out of context, that was then but things have changed, look at this good thing that was done and ignore all that rape and murder stuff. They soon realised I was just being an asshole

I've been openly mocking religious people on Facebook for years and some family members sometimes don't like it, but my generation of cousins are all pretty much atheists despite their parents. I like to think I've had a little to do with it by always staying rooted in facts and letting them read.

I stopped "believing" at a very earily age. It just never made sense to me even as a small child. When around family members I found it just easier to either ignore them and just stay quiet, or jump into the discussion I knew it as well as they did
I just knew my time to get away from all of it was coming, and in the later years would just sigh internally and roll my eyes when they'd start. Once away from them I actually found myself, not definend by their vision of what I should be.
I never looked back and am happily away from it completely. I can still talk circles around most "modern" x-tians. They hardly even read the book, but depend on what the pastor/priest tell them.

My family knows my beliefs. They are all Baptist and Pentecost. They used to talk to me about it, but I told them that I respect their religious beliefs, but I could never be Christian, but we are family and I bet we can respect each other and all get along. We have so many things we love about each other, that we can all be tolerant of each other. They are all fine with it. If they want to say a prayer, I sit and wait till they are done, then we go back to whatever we were talking about. It was more of a struggle with my dad. I finally told him that if he could not refrain from preaching at me, every ti.e he saw me, I was going to leave until he stopped, then I would come back over. He never quite stopped, but he was more respectful, and I am extremely tolerant, so not much bothers me.

Mouth shut. Say nothing. They are not reasonable, emotionally mature people. They will not live forever.

I actually got my sister to stop and think for a minute. She was going on and on about how she just doesn't understand how I can not be a Christian, when I stopped her.

Me: "Correct me if I'm wrong, but you believe that the Bible was inspired by God but written by man.:

Her: "Correct"

Me: "You do realize that the main Bible, the King James Version that most people go by was written by a tyranical king whose motive was to control the masses. Some historians even go as far as to say he had syphillis including the mental derangement that comes from it."

Her: "Wow, I'm going to have to think about that."

It probably won't change her mind, but at least it got her to think. She also admitted she is confused about God never having a beginning or an end, and that evolution (which she believes in) makes as much sense as the big bang making nothing into something.

Mainly ignore the subject unless they are giving me their “I’m heartbroken because you are going to hell” look. Then I tell them to knock it off.

I'm right there with you in terms of being the "black sheep" of the family. I find that keeping the peace is more important than being right, in this case. So, avoiding the topic is best...unless a family member wants to have a serious, but respectful discussion about it.

I just avoid the subject coz we only end up arguing. They respect my views and I respect their delusions. It works for us.

I usually only pipe up when they're trying to discredit facts or science in the name of religion.
