I saw some of the video. I saw some guy go down very hard after being struck in the head with a pole of some kind.
The “Nazis” reminded me of European skinheads, but wore their hair longer. They had black t-shirts with a gear logo with a pitchfork in the middle, it looked like.
The protesters weren’t screwing around. No shouting matches, they just RAN straight at them and started whaling away.
The ANTIFA/BAMN black-bloc leftists are the ones dressed in all black, with long hair and black face coverings, doing the bludgeoning. The clip you saw shows them bashing pro-white women with big wooden weapons.
