My dad was a JAG officer and was moral and ethical to a fault and very much an Eisenhower Republican (Ike was a personal friend). He was against racism and intolerance long before it was cool to be so and became an Independent when the parties flipped over racism in the '60's. My mother grew up a Democrat in the Deep South and stayed a Democrat when the parties flipped (unlike her sibling). She was always quite feisty and never met an argument she didn't like.
Both of them would be outspoken in their disapproval of Trump and his defenders/apologists/enablers, just as any moral and patriotic American should be. My dad wouldn't confront anyone over it, but my mother would get right in the face of anyone who expressed support for Trump, his beliefs or his demeanor. Guess who I took after in that regard.
