She's saying the Nazis are dangerous and have to be stopped by any means necessary, like 'direct action'. Apparently the Antifa groups ('BAMN - By Any Means Necessary and affiliates) planned to arrive with bats/clubs/knives and assault the neo-Nazis and beat them to a bloody pulp in order to prevent the spread of neo-Nazi ideas. Kind of like saying 'anyone who doesn't practice tolerance needs to be lynched'.
Oh well, leftist retreads battling rightist retreads, made for TV action and excitement!
