In their own words:

Let's get one thing clear. Antifa is an Anarcho-Communist cause. Those on the left who call us "patriots", step the F*** away.

Anarcho-Communism is 2 steps. Anarchy to install full Communism. Anarchy is our demolition crew. Communism is our construction crew.

Remember that and quote it the next time some Leftist bubble head tries to tell you the "altright" caused all the violence at Charlottesville and its opponents were merely peaceable anti-fascist, anti-racist.
