[What this doesn't say is that the "real" Antifa is a group with it's own devious agenda.]

Twitter has shut down multiple accounts that it says were operated by a white supremacist group posing as liberal groups encouraging violence.
Twitter said the white supremacist group Identity Evropa used one fake account, @Antifa_US, to call for violence in majority white suburbs, in the name of the Black Lives Matter movement. The account's removal was first reported by NBC News.
