Religion/politics side note/TL DR warning: my mom REALLY dislikes Romney. She wasn't a fan of Bush, but respected him in the general ways a lot of folks tended to at the time ("he's a man of faith...he believes in what he's doing...etc"). A lot of it has to do with her visceral dislike of Mormons in general. When I was growing up, both my parents put a lot of religious emphasis on teaching me to dislike and oppose three theological views: Calvinism, Jehova's Witnesses, and the Church of Latter Day Saints. At the time I could understand the basic complaints against the first two on a biblical level, as in if I got into a debate (at that time) I could quote the verses I was spoon fed. But the explanation I always got when asked why I shouldn't like Mormons was "they're racist against black people."
I learned more about Mormons in highschool once I left home school, and even made some Mormon friends. It's certainly true the religion was rather racist for a time, but today I can't really say I believe they're officially racist anymore.
Naturally, my mom still believes they're all racist and cannot stand them. My mom has Jewish friends, Muslim friends, hell she even has Jehova's Witness friends now; she's never been an angry or mean person. Yet I've seen her close the door on Mormons who knock on the door (without saying a word), she refused to invite a Mormon family to a big dinner event she hosted for the other families on their block of the suburbs, etc.
(My dad may not like Mormons, but he's too nice in general to treat anyone bad unless you're from Ohio State)
