It's the tagging that's a real eye sore. The same thing over and over again with no artistic merit.
And people saying they're ok with graffiti and vandalism are really saying that they're ok with other people's property to be graffitied and vandalised, not their own.
> Graffiti happens at the intersection of ambition and incompetence: people want to make their mark on the world, but have no other way to do it than literally making a mark on the world.
We don't think it's ok for people to "paint or sticker or everything they want", we think this is particular type of alteration is ok.
At an extreme if Banskey wanted to graffity something of mine I'd be incredibly happy so this is just plain incorrect.
Probably not big on people tagging my stuff, but this is not what you are implying.
Visual pollution is a thing, as you seem to agree since to you graffiti is vandalism (compared to invasion of property rights for instance), but by this standard why does a business owner get to then visually pollute outside of their property?
