You don't get to tell me what I find beautiful.

Right. That’s the point. In public spaces, the public has chosen what it believes to be beautiful. Illegal graffiti is one person forcing their aesthetics on everyone.

Plenty of cities have surfaces that are open to being grafitti’d. In those cases, the artists bothered to think about others before taking unilateral action.

For private property I agree with you, the owners have it how they want to have it.

When it’s mattered, I’ve showed up. Or signed petitions saying something is ugly and would benefit from being replaced by just about anything else.

Plenty of communities embrace their mural and graffiti culture. Plenty don’t. Imagine if someone who doesn’t like murals went around whitewashing painted walls.
