I also have family who support him. It is the worst feeling seeing people we respect (or at least had respected) turn into Trump sycophants simply because of identity politics and hatred of anyone who isn’t them.
It shows who they have been, this whole time. And it’s like being shot in the heart.
Literally nothing is disqualifying for his supporters. This is what they want and believe. This is what a lack of proper critical-thinking-based education wreaks.
If Kamala wins, and the house gets Democratic control, this nightmare, for now at least, will be over, despite any threats Trump and his ilk will lob. If either of those turn out the other way, I do not expect this will end well.
