I'm thinking this has to be true. I have a hard time believing that there are people who are familiar with all of these incidents--the thing that provoked the memes--and just happen to have the worst take on all of them. They're so 180-degree wrong on each and every one of these subjects that they'd proudly pile them into a pile labeled "just hate" (and allow this to be shown to other people).

Falsus in uno, falsus in omnibus is supposed to be a warning, not a commandment.
