My entire family is like that. 125+ IQ, all of them. And every one of them is liberal. That said, I think I know why. Because they are busy people, they really dont have that much time to look into the issues deeper than, say, one level. They dont have time to read up on things either, so they trust the MSM and the narrative.
I am the sole Conservative among them (2 parents, 5+ siblings). Every family gathering is a struggle, they will spout off whats been spoon fed to them, and these days, I just sit and take it. They always look at me, knowing I disagree, waiting to see if I say anything (I just happen to be the most informed... oh, what a coincidence).
I have stopped trying to convince them about our side of any particular issue, but one thing I can get them to agree on is how terrible the MSM is. Once I get that hook into their brain, I can lead them into understanding how the MSM is all about Narrative, not Truth. And if I can demonstrate a few narratives that "everyone" knew was real, that turned out to be false... it gets them to thinking.. and I just leave it at that. To do any more would be to make them defensive, they dont want to be convinced by SOMEONE ELSE, too much resistance, but they just might figure things out for themselves......
An occasional zinger will come your way.Use it in a polite, even jovial manner.
Once I was in a conversation about global warming with a dear colleague. She said that most scientists feel that global warming is real. I said, “ See, they ‘feel’ that it’s true, which implies belief, not necessarily real facts.
She was quite impressed, it seemed.
