I’m going to guess that your Mom, like many people of her era, watched network news every night, or at least regularly with no balancing input. Everything she saw on TeeVee just had to be fact from those nice people who read to her each night. I’m not making fun of her, because my own father, in his mid 90’s is glued to the network news. A once Republican, now is not, and hates Trump.
With respect to younger generation Democrats? My extensive experience demonstrates that there is no talking to them. Their minds are shot. They are incapable of reason. They are incapable of reasoned, rational thought. I have long ago given up with having a political discussion, or a social discussion with people who have lost the capacity to reason, they can only defend their tribe, their clan, at any cost, no matter how absurd.
