I think there is a lot of nuance here. Just as councils and developers can construct ugly buildings artists can also add ugly work to walls.

I agree there is a spectrum. On one hand you've Banksy or Basquiat adding to a flat grey wall and creating art that has a political voice or some artistic merit and the other you've some twat scribbling hate symbols on a historic monument. I don't have on ideas on how we can ensure one and not the other though.

It sounds like you're saying the only thing ugly about tagging is when it contains objectionable political content. That's not really responding to the complaint here, which is that the vast majority of it is low effort, low quality tagging that makes things aesthetically uglier. It's easy to go out with a collector's eye, cherry-pick the good stuff, and put together a slideshow that makes it look like a public amenity, but that ignores the overall effect of wall after building after block of proof of Sturgeon's Law.

Is it ignorable? Does all the terrible stuff just disappear into the background, or should we care about how it affects the experiences of people who have to live with it and walk past it every day? I think that's the question people are arguing.
