Jack Curtain lives in SF, which is most likely the most pro-gay city in the world. I find it a bit hard to believe that he's that bothered by homosexuality in any way, shape or form. In SF, you see behavior like that all the time and WAY more provocative than dudes kissing.
That being said, if this is true in any way, I kind of agree with joe budden that they (the dudes who kissed) may have gone out of their way to make people feel uncomfortable at a skatepark.
