How do I deal with a religious family as an atheist?

As a fellow Atheist, I can see how that's frustrating. If they're accepting of your non belief, then you must be accepting of theirs to keep the peace. They should respect that you do not want to talk about things religiously and not give you hassle if you choose to leave religious discussions or events. Being open about it all with them may help you.

Talk to them, express you are not a religious person and that you accept their beliefs and tell them you feel unhappy with religion being forced upon you.

From personal experience, I just keep my opinions to myself and kind of go along with it ( I haven't told my own family yet). If you're not comfortable with that it depends on multiple factors: do they know you are atheist, are you comfortable with them knowing, what is going on with your family (are they saying that you just need to embrace God, ect. or are they okay with it). Like most things, how people deal with things are unique to their experiences and circumstances.

If a conversation were to arise about beliefs, flat out decline to comment. There's no reason to get involved. You don't want them to give up, and you don't want to be converted. Just let the conversation die on its on when it comes up.

I would tell them about your beliefs and that you don't feel comfortable going to church with them.

That depends on how open-minded both sides are. It's important to accept people for who they are and not who they believe in (if they do). So I'd say regularly talking things out to gain the other persons perspective and better understanding is one of the key-points.

This question is difficult for me to answer but I will try. I calmly ask my family to please respect my opinions. If they continue to provide me with religious based advice, I ask them to please give me space. Personal boundaries are important.

Don't really put your beliefs out there. Respect the religion your family follows and do as it requires, but leave your own beliefs to yourself. That's generally what I've done.

Although it might be hard, it is best to tell your family about your feelings. Hiding how you feel and being uncomfortable about it just makes the situation worse.

I have a religious family too, but if you live with them you have to respect their habits and beliefs, sometimes sharing that kind of moments with them, that doesn't mean you aren't an atheist, you can tell them that "you are an atheist but respect their religion" if you want, but I recommend to wait until you aren't going to live with them or you are 18 years old to avoid some problems
