Here is a better desc to describe what a Feather Nazi is: A person that believes all dinosaurs/dinosauriformes had feathers/feather-like integument. And no, most if not all Feather Nazis don't think dinosaurs are birds though some think that our understanding of what and what isn't an avian dinosaur should be moved further into dinosauria, making such groups like dromaeosaurs and troodontids count as aves)
