This is not a religious debate so let's not make it one.
I'm an atheist and have tried to keep it hush hush to my family because I simply don't want to deal with the drama. I know that religion causes rifts so I figured it was best to just not even mention it. Well two weeks ago my dad asked me if I believe in God and I said no, and now tonight my sister just did the same thing

I'm not going to lie about it so I of course said no. Being fairly strong Christians, they both tried spewing reasons and "facts" that prove Christianity and tried telling me that I'm ignorant/need to do more research. I just went along with what they were saying and "mhm"ing so they would let it out and shut up. I just KNOW that my sister is going to blab about it to her pastor because she sees him every week for counseling. They're probably going to pray for me or something.
Last night I was listening to my grandma and sister have a conversation about atheism and I was getting so pissed off. My sister said she talked to a guy at work who's agnostic and said she couldn't wrap her head around it. My grandma agreed and said that we know God exists so why wouldn't they believe

them being Christian doesn't bother me but the ignorance does, and I know that they're going to try pushing it on me especially now. My sister just said tonight that she wants me to go to church.
How does your family feel about your (lack of) beliefs? How do you deal with it?
