To be fair, it's a valid point. Having pink hair is a much better sign of sexuality than being married for almost 4 years with a 2-year-old daughter.
I just figured if he could make some stupid stereotypical generalization, so could I.
Also, his hair looked more red than pink to me, and I don't know if I've ever seen a pink-haired gay person anyway. That would be like me wearing my Queen shirt literally. I've always seen the crazy hair as more of a punk/alt. rock thing than a gay thing.
