Well, first off, your comparison example is not apples to apples. The guy out jogging doesn't have the reason for embarrassment or shame that the morning wino has. He's doing something "silly", not something self destructive.
But secondly, your exampl stereotype doesn't apply. My experience is ~NOT~ that the typical homeless drunk is black.
I'm really enjoying this thread. There's more racist notions in some posts than McGruder's dumb cartoon. Very interesting to read what people THINK all black man do. I live in a predominantly black area and have not seen a wino as described by the above.
