For me personally, I haven't discussed my atheism with very much of my family. I think my sister knows, my nephew who is also an atheist knows, but for the most part I'm not open about it. I'm not super close to my siblings but it's just not something I want to bring up. I'm not going to tell my mom, either. She hasn't been in good health lately and I don't want it to affect her. I know it would because she'd be worried that I'm going to Hell. It's too bad that people's belief in Hell makes them worry about me going there to the point where I can't be open with what I believe.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
