Agreed. Additionally, when someone says something latently bigoted or hateful, it's easy to just let it slide because we all have our failings and societal progress is slow. Whereas maggotry is about openly embracing those failings, taking on additional types of failings from other people, and then socially validating it all as a purported political movement. But the only real thing tying it together is frustration with the world culminating in lashing out, which is why when they get into power there are no actual constructive policies in any political framework [0]. (apart from lining the preachers' pockets of course, and now apparently a holy war)

nit: I wouldn't call it "mask off" though, as if it's been there the whole time. I'd say it's more like there is tiny a kernel of that (and let's be honest, who doesn't have this in some form or another?), combined with a lack of willpower and critical thinking, that causes them into give in to the siren song of easy answers from mass-personalized propaganda.

[0] ancap and religious fundamentalism are the only frameworks I've been able to find that fit the maggot movement, and they're not particularly constructive.
