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. 
“Both ‘anti-tankie’ and anti-statist” is redundant. You cannot be anti-statist and not “anti-tankie”, because “anti-tankie” is opposing socialist states. Anarchists only criticise socialist states more often when they’re talking with people who defend and excuse them, which is why you see the assymetry. In a regular anarchist community of mostly anarchists, both online and especially in real life orgs, it’s actually quite the opposite.
