Thanks for your input. I’m sure there’s some truth to your hypothesis. Unfortunately, we are not dealing with the colorful political graffiti murals like you might see in some places.
I’m from a small town in Georgia – there’s still so much tension between the whites, blacks and hispanics in this town. Most of the writing is racial or gang related. There are some graphic pictures – one of a man with a gun pointed to his head. I took a group of middle school students to the overlook while teaching them about our river system. Let’s just say they were way more interested in the graffiti.
I agree that graffiti can become part of the character of a place; it can be interesting and sometimes something beautiful to look at. But when the graffiti comes from bad intentions, it might be best to cover it up and try to prevent it.
