Even the RAT “Nancys” like Princess Nikki here don’t have a high enough I.Q. to come up with something other than “Hitler”. What’s the matter with Atilla the Hun? Princess Nikki probably never heard of him.
Hitler is the few names the Left can rely on for people to already know and understand that they are supposed to hate. Any other and they’d have to explain it and the comparison is ruined.
They might toss out “McCarthy” (or Bull Connor!) once in awhile, though!
