Just went through that with an elderly neighbor recently.
She broke her foot and is in poor health, so we were walking her dog twice a day cause we are nice like that. She was always praising us for being such good people and a godsend to her.
One day, she made a comment that she thought Trump was doing a great job and I gently tried to explain to her that he was ruining our lives and countless others out there.
I was hoping she would have a moment of introspection, but no. She just immediately went on about the democrats, how we get offended too easily, and how she thinks I swear too much but she doesn't hold it against me.
Everything except: "I'm sorry. I didn't realize."
Told her we no longer feel comfortable walking get dog.
Cue the waterworks and the "What about me? I can't walk!"
It's not worth engaging with these people. There is something broken in their brains.
One thing that worked with my partner was asking them if they had a racist or a mean relative and asking them how they felt spending time around them when they were kids.
We haven't talked to his parents since November and he says he ain't missing them at all.
Toxic-ass motherfuckers.
