I know what you mean; I think it would be hurtful to people with Parkinson’s, but whatever, I luckily don’t have Parkinson’s so not much point arguing it.

Characterising involuntary but normal phenomenon as intentional or artistic is maybe a little less gross, but still asinine.

That seems like a very bizarre take. Isn’t that a very common artistic device, to find creative interpretations of natural phenomena, and to imagine intention where there is none? I mean, art is subjective so maybe that’s just your personal taste, but it seems like a strange thing to be offended by to me.
