I’ve transformed my mother from a person who would only refer to Spanish people as "wtbcks and would yell the n-word at the TV while watching cops to a person who calls out white people explicitly, says black lives matters, cheers on cops getting wrecked, and says that rightoids need to be purged and it’s okay for cities to be burned in the name of social justice. My dad has explicitly said to me that Socialism is good and cool.

This is incredible! Your work in pulling your parents leftward, let alone that far leftward, FAR outweighs any negatives from your single vote for Biden. Please don't beat yourself up too much over this, you are doing great.
