Condering that the art is unharmed, and they glue themselves to the gallery waiting for the police while explaining what their goals are so that passersby film them to spread the message, I’d say that they are, frankly, pretty distinguishable from vandals, or do you know of other vandals that do that?
I’m gonna call bullshit on “too toxic.” There were literal riots over getting civil rights. There were literal murders over getting civil rights. A lot of the reason why MLK looked so good was because there were those who took extreme actions, and his nonviolent protests would sometimes be treated the same as the violent ones. But you think a stall-in would be too far? Should we use the Suffragettes instead, who also vandalized museums (worse than these guys)? Was that too toxic? What a silly argument.
