You assume these people read what you read, listened to what you listened to. They very likely did not.

I assume that when I told my parents 57 times specific reasons trump was a terrible person and they ignored me that I wasn't hallucinating. I also assume that their comments like "the media treats him so badly" is a result of them watching the news like they have for 40 years but in this case choosing to think that it was suddenly unfair, unlike every other time in history. I assume that when my sibling told me they are marrying a trump supporter after years of claiming to hate trump and care about the future, they did so out of a similar tendency to ignore reality. I don't think trump supporters are innocent. I think they're extremely mentally lazy at best, dogshit people at average, and malicious sociopaths at worst.

Ps. My mom actually had the gall recently to say she didn't know these bad things about trump or that he'd be a bad president. Which even if I hadn't told her myself many times, is not excusable. She is literate and has cable and the Internet. All are things she used to use in order to educate herself to a small degree. Now she wants to feign ignorance when I know for a fact I worked pretty hard to educate her. My late grandfather was the opposite. He said he liked trump but then I told him he had several wives and allegedly raped one of them. At that moment he changed his mind. Pretty fucked up almost no one else can do that, literally regardless of what information is brought to light.
