A funny thing somewhat like that happened to me too. Last month while I was wearing a tight pair of black jeans, handcuffs, a wallet chain, mirror sunglasses and a tight black t-shirt. I was about to go on a date with a yuppie girl that liked metrosexuals (I wanted to get laid real badly that night). That day, an ethnically-charged assault was attempted on me by a fat, out of shape white kid. He got out of his car and started saying "Pound the "African American Homosexual" (Although his vernacular was different) and advanced towards me.
Unlucky for him, I've been practicing eastern martial arts for a year and a half, and before, I used to box for half a year. You add 2+2 together.
If that was my kid I would have punched him in the head first. We really do have to ask where the parents were in this. My kids can get into pretty big trouble and I always have what I think is an appropriate, fairly calm, response. But I just can't imagine how I'd go off if I ever saw one of my kids in a shirt like that, with an attitude backing it up.
