Check out this video from about 1:15 on, as a brass band play the leftist anthem "Bella Ciao" to drown out #ProudBoy neo-Nazis who showed up at a #NoKings rally in Atlanta yesterday. Not only is it incredibly heartening, but the band SLAPS.

@pluralistic @inthehands At any event where the Proud Boys show up, they need to be met by a loud klezmer band.

It is now all of our national duty to join a klezmer band

@jongary @pluralistic @minmi @inthehands hey! I was in a Klezmer band for a decade! Who wants me near DC?
