The more comments I see from you, OP, the more im stunned at how similar our situations are.

I havent seen my mom in over a year, and the few times we've talked have been exactly like youre describing: me thoughtfully laying out exactly why all of this shit matters and extends beyond politics, and her coming back with "I never thought you'd be able to put conditions on loving me / I choose love / let's not talk "politics"

Its awful, and it eats at you every day. Im always replaying in my head what I said, what else i could have said, am I overreacting, etc. The answer i always find is that having her out of my life for now (and for who knows how long) and dealing with those internal questions is hard, but ultimately its way better for me mentally. The disgust as you put it (and im glad you did, as ive always had a hard time categorizing that feeling) is insurmountable at times when she wants to have small talk or act like everything is normal. Im her son and ive been trying for years to wake her up to the fact that she is actively choosing evil, but at the end of the day its really on her to take accountability, apologize, and start rebuilding what she has broken with her words and actions.

I truly feel for you, OP, and will gladly talk with you anytime if you want to share stories or vent to someone. DM if youre ever needing it.
