The kind that thinks communism is the same as nazism and thinks communism is when the government does things.
I hate liberal brain worms.
They seriously do as much damage to the left as fascists by punching to the left and spreading capitalist anti-left propaganda. They overall weaken leftism and help fascism.
We need more left unity, folks. Fash ain't gonna bash themselves. 
I went on a date once with someone who seemed really cool.
Then put of nowhere they went on a little rant about "tankies" and I realized they weren't the cool kind of anarchist.
There was not a 2nd date.
