I think graffiti is stupid. Obviously whoever does it has no respect for other peoples' property. Why should we listen to what disrespectful people have to say. There is absolutely no reason for someone to go spray paint a building. If they have this much time on their hands then they should go get a job or do something to better the community like volunteer work or picking up garbage. If they really cared then that is what they would do. They are just trying to get attention and a rise out of people.
I never really thought about how much work it is to help protect what is yours until I read "fortified Ghettos." People put so much time, energy , and money to put up security fences, cameras, steel door, and even guard dogs. There is no reason why people have to do this. People need to learn respect for other peoples' things.
