No.
For example, I’m WAY to the left of both liberals and democrats, so I identify as neither, and I’m not a Nazi.
But I’m guessing what you MEANT by “people who don’t identify as liberal democrats” was conservatives, because most conservatives, liberals, and democrats think liberals and democrats are the left. (They’re not; they’re the middle.) Anyway, the answer is no, I don’t consider all conservatives to be Nazis. Dangerously wrong about essentially everything, but not actually Nazis.
