You really aren’t going to get very far intellectually with a rigid ideology that equates disagreeing with Trump to a mental illness. I’ll happily admit that Trump is right about some things, whether or not you’ll admit that he is wrong about some others.
I can't think of many things he has said that I would agree with. On top of that he's usually angry and spiteful in pretty much everything he says. Why would I not be in constant opposition to that?
There's no TDS (whatever version of it you like). Trump himself is the disease.
But yes, right-wing people still defending him, because he may still speak something they like about some issues, is like an abused partner telling the doctors in ER: "but he is a good husband"
