AIO? Birthday card from my dad

He's an undiagnosed so-and-so, abusive, functional addict, and utterly, permanently fixated on how all three of his wives/baby mommas ruined his life and so did his four children. Our mothers' crime: fleeing abuse. His children's: leaving the nest years later. Note: I have never once mentioned his estate/money/will/inheritance issues. He is 78, not senile, and likely to live another 10-20 years due to very good genetics. He began receiving a lot of extra money via survivor's benefits after my mom died (increasing his monthly SS benefits by about $500/month), and he continually manipulates his demented 85 y/o MAGA brother in Florida to send him gigantic checks (5k or more at a go, several times a year). He is hung up on the fact that I have been receiving benefits from the government since I was 17 as a disabled individual. I have maintained some kind of employment consistently as a teenager and adult in addition to my benefits and education. I've never held a "regular" full time job, but neither has he.
