I've seen this too. Right after 2020 I was in a gas station that I stop at regularly and I've seen the lady at the counter a million times. I catch the end of a conversation she's having where she's shitting on Trump. So as she rings me out I ask her

So what policy of Trump is it that you don't like? I don't mean his personality. What did he do as President that made you hate him so much?

And the bitch bluescreened. She went kinda slack jawed and deer-in-headlights staring right past me for about 8 or 9 seconds before shaking her head and stammering out "I just.. I don't like him. I DO NOT LIKE THAT MAN." And that was it.

If you hold a very strong opinion, but are unable to articulate why you believe it, then you are likely a victim of propaganda.
