I can't see how you can argue.
Vanadalism has been a crime for a long, long time. It's been a crime because it is selfish to dictate what you think is "cool" for other people. In many ways, it is against free-speech. If I posted a campaign for something I believed in and it was spray painted over illegally, this would be hurting my own voice.
Grafitti artists are selfish because they are fine with other people's possessions being trashed if the outcome is good. Even though they may not mind, others definetly do. Arguing otherwise is just idiotic. Now, if they argue that they don't care what others think or want, if they honestly believe that everyone's property belongs to everyone else, then they are arguing for anarchy...
Think about this. If someone came into your home, knocked down your walls, broke your bed, burned your own art, and shreaded your writings, you'd be upset. Saying otherwise is a lie. If someone loses everything they own, they aren't going to shrug it off. Now true, this is making grafitti sound like a terrible crime, but in truth, allowance of grafitti just leads to this road. If you allow people to modify or destroy property of others, then you are allowing this. What is the difference in spraying graffiti on the outside of a building then on the inside? Sure, ultimately, both can be repainted, but it is still cruel to do. It is irresponsible and cruel. You are ruining someone's property for your own pleasure and the pleasure of a handful. This just isn't right. Please explain how it isn't selfish and cruel to ruin someone's property? And again, EVEN if you don't care about your property, most people do. Grafitti artists have no right to impose their opinions on people. This stifles freedom.
I have no sympathy for those who care nothing for others like this...
To think otherwise is childish, as said by another poster earlier..
Peace. :m:
