I think that the whole concept can extend into things like their views on homosexuality, race, religion, etc, too. I mean, I honestly think a LOT of homophobes and transphobes get these internal feelings of "EW, I WOULD NOT WANT TO DO THAT". Then, because they haven't been taught out to separate icky feelings from whatever causes them, their instinct is to label whatever made them feel gross as evil. And then they twist their world view to confirm their viewpoint.
