How about no. How about people use curbstomp whenever they damn please. I'm very well aware of what you're implying and what you're trying to do here. Poison the well, police the conversation. Just like the OK sign just means "ok", curbstomp just means curbstomp. The fact that someone somewere used these things in a racist context means nothing, as these words/signs are not racist at all. Racists also use toilet paper, are we going to ban it? How about air or water. No, all of these attempts to police and cancel speech need to go to hell.
There was a clear implication, let's be honest here. Extreme violence is a normal part of our culture - young kids watch hulk smash violently in marvel movies and no one bats an eye. The reason strong offense is being taken here is because of the racist context of the violence in the movie.
