You are not only condoning it, but also helping to legitimize it. Just like the idiots that refer to it as art. It's not art. It's vandalism, and like all vandalism, it is a tearing down of society and it's structures.
I agree completely that the real thing is vandalism, and it is a tearing down of society and structure. I also believe it is not art but I do believe it is creative, a creativity that is seriously misplaced. I believe that the folks that do it are degenerates, but they posses talent. Many talented and gifted people are sick and need to be locked up. There are gifted people that do far worse than paint boxcars. I am not legitimizing graffiti, I would turn someone in the minute I seen them do it.
However it is a fact of life, it is a reality. I model as close to realism as I am able with my feable skills. You choose not to and that is fine, however many of us do. In your modeling world, if the streets are always clean and free of litter, there isn't a broken window in site, and your scenes resemble a norman rockwell painting there is nothing wrong with that. I truely mean that. It is your modeling your world it should be the way you like it or want it.
Some of us prefer the dingy world of reality. I like to think of my modeling as a snap shot of the real thing. Rust, dirt, grime, dents, scratches, patches, and yes graffiti are all visible on my models. This is how I prefer to see my model. I have buidlings with broken windows, because people throw rocks. When I get rolling I intend to have junk because people are messy, and litter because people do not pick up after themselves. I also will have norman rockwell scenes because that exists also, I will have kids playing fetch with there dog , because that is reality.
Crime is a reality, In fact you have given me an idea for my layout. Maybe just maybe I will have a tagger in cuffs on the ground or in the jaws of a K9 dog and a few rattle cans layed about, Why because that is reality also.
If I choose I model graffiti or not, wont change what is going on. They are not seeking my approval, nor are they even concerned about my opinion of their transgressions. I am against all crime does that mean I condon it by accepting its reality? If I stop accepting it will it go away?
