Revolutionary anarchists hate Repubs more than they hate “Progressive” Dems. For one thing. For another, they can be hired under the table by Dem operatives. Just an idea.
Yes. There's really at least two "brands" of anarchist, and both of them hate the right. One is the traditional anarchist movement, firmly rooted in the left. Then there's the national anarchist, more linked to 3rd position and nazis. They serve as glue between extreme nazist groups and extreme marxist groups, like the democrats have become.
