My mom made me confused

[Der/die AtheistIn]

I didn't ask her to do a list, but when she talked to me she said that good atheists follow some rules of Christianity.

Then ask for the rules that "good" atheists don't follow and see what her response is. See if the rules are really from god/religion or if it is coming from her belief system.

She doesn't claim that the rules need to stem from Christianity. She thinks that Christianity is good because it has good rules (not every single rule) that apply in every context.
