Why are people against graffiti?

In a couple of my neighbours town that's all there is to tap unless you count kick marts or krusty burgers which I don't like tapping.

I don't like tapping brown houses grouped together either, I find it boring but if that's all there is to tap I'll do it, I'm not going to loose a good neighbour because of it.

I don't mind what my neighbours tap in my town, but if anyone objects to me spraying in theirs just pm me and ask me not to,no problem. :D
