What is Frank Miller saying here?

The “Occupy” movement, whether displaying itself on Wall Street or in the streets of Oakland (which has, with unspeakable cowardice, embraced it) is anything but an exercise of our blessed First Amendment. “Occupy” is nothing but a pack of louts, thieves, and rapists, an unruly mob, fed by Woodstock-era nostalgia and putrid false righteousness. These clowns can do nothing but harm America.
