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.
