Yes, that's true. But leftists just see anarchism as the train they get on, to ride to the communist paradise. They are only against the state, if it isn't a communistic one. Which is a sensible, logical stance: anarchy as a tool for overthrowing the government and replacing it with a "better" government. Right-wing anarchists see anarchy as the paradise. So, they are eager to help the left-wing anarchists overthrow the government, and don't realize that they are just useless idiots and will be the first ones against the wall.
