Graffiti comment

In my opinion, Graffiti is a way of art, that defines the feelings and expresses ideas and thoughts of the creators.
In the beggining, Graffiti was created to define the territories of the gangs, but some time later, some art critics started noticing that those "paintings" were actually great expressions of art and some of those graffitis are even exposed in art galleries.
Nowadays, famous people spends large accounts of money buying graffitis to expose in their houses or private locations, as the text shows, and that is one kind of proof that graffiti can be useful and beautiful, because it is a great way to express our feelings and we dont need any type of studies or learnings to do it.
It´s true, in the other hand, that one neighbourhood with graffitis can be a litle bit scary if you don´t know that place or the people that live there, but its ridiculous to say that graffiti is an "eyesore" and an act 0f vandalism.
In my opinion, it shouldn´t be forbidden to do graffitis, but start creating special areas where anyone can paint whatever they want, despite of loving that way of art, i think it is a crime to paint in areas like building or spaces that dont belong to us.
I think also that it still exists too much prejudice against this art, because most of the people when they watch one "tagger" paint on the streets, still think that it was a junkie or a delinquent the author, and don´t believe that some artist can earn money and live by doing those marvelous creations and showing them around the world.
