I F(19) was talking about religion with my mother (F45). She was saying how she was thinking about believing in God but not belonging to any religion. For context she was raised Christian, raised me Christian, but i left christianity and became agnostic. We were debating about how evil and God can coexist, and i brought up the question of why would God give an infant terminal illness if he's supposed to be all loving. She then said to me 'you reap what you sow and some mothers drink/smoke/consume drugs during pregnancy.' I told her that was quite a fucked up thing to say because those sorts of pregnant women are very rare, and even pregnant women who did not of these things still go on to have kids with these conditions. She said the classic'only God understands why' and I pressed her saying how messed up it was to say that, and how she would never say that to a mother's face.

She then said 'God blesses good people and their generation.' I asked her then 'if someone is poor does that mean they're not a good person?'She was about use her sister who passed of cancer as a crutch to support her argument(in the past she's implied her sister wasn't a godly person in her youth to say thats why she got a terminal illness. I told her she's been absolutely brainwashed, she screamed at me for disrespecting God and now she's stomping around the house in a fury. She wants an apology, AITA?

TLDR:my mother used the argument that some people who have kids with terminal illness'reap what they sow' so it's deserved as a response to me asking her why God would give kids terminal illness. She now wants me to apologize. AITA?
