When it's pointed out to a Leftist that the Nazis were Socialists, the Lefties always come back with, "The Nazis were nationalistic, therefore they were right-wingers" (assuming they don't just call you names instead).
Nationalism = love of country = patriotic.
So, what the Leftists are finally admitting is that, as Leftists, they cannot love their country and are unpatriotic.
Leftists continually get in trouble this way because they are too stupid to think even one step beyond what they've been told to say. It is the thinking of a child. That is also the very reason that they are Leftists.
