I think what most people with tattoos are trying to say here - is not to judge all of us by the measure of some. The guy with the skull on his face might very well be a dumbass. It doesn't mean the cardiac surgeon with a tattoo of an eagle on his back, is. Or it may be the other way around. Who knows.
The lady with the bleach blonde hair may be a bimbo - does that mean all bleach blonde women are bimbos?
I'm not ready to make that leap, and I'm a little surprised that some people in this thread have made that leap regarding people and tattoos.
