I really, really hope AfD gets banned. Germany has strong anti-hate protections, but enforcement on small groups is avoided because they're too small and not worth the trouble/attention, and enforcement on large groups is avoided because they're too large and powerful, so it's barely useful.
Canada often does the same thing.
Yeah, I kind of wish there was another word for the idea, because it's a bit confusing. I think originally it was "in reaction to progress".
Big and small c conservative is sometimes used to make the distinction in commentary, with big C being the reactionary stances that are common in right-wing parties that call themselves "Conservative", but I don't think everyone gets that either.
