The American Civil Liberties Union has a long history of defending the First Amendment rights of groups on both the far left and the far right. This commitment led the organization to successfully sue the city of Charlottesville, Va., last week on behalf of a white supremacist rally organizer. The rally ended with a Nazi sympathizer plowing his car into a crowd, killing a counterprotester and injuring many.
After the A.C.L.U. was excoriated for its stance, it responded that “preventing the government from controlling speech is absolutely necessary to the promotion of equality.” Of course that's true. The hope is that by successfully defending hate groups, its legal victories will fortify free-speech rights across the board: A rising tide lifts all boats, as it goes.
