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.
They did. They do. They probably will in the future as well.
But, it seems as though people care more about art being faux-vandalized than they do about the planet dying, so those don’t make the front pages, or you would’ve known this.
