How would referring to one as either a nazi or neonazi be a thing that is grounds for being banned?

Post nazi-Germany...'nazi 'is simply a word that combines several less than stellar philosophical/political beliefs into one handy word.

Might as well ban someone for calling another person a Catholic.
