That can be your point, and with that framing almost anything is permissible! My point is generally to let free, open democracy run its course without putting our fingers on the scale too much.

I'm not scared of people doing a salute in the style of a movement that's been dead for almost a century. I'm not scared of communists flags or chants, or people chanting from the river to the sea. I think it's all healthy as long as it's non violent. The argument that it leads to violence is not logically sound and very minority reportesque.
