The reason SOME, but not all, categories of persons are included in hate crime legislation is because of a pattern of crime against that particular category. There is a pattern of "gay bashing" in our country, resulting sometimes in death. There is also a pattern of crimes against blacks. And so on. There is no pattern of crime against white males in our country, that we can tell. They are the victims of crime sometimes for other reasons, and there have been instances of white males attacked because they are white males. But those instances are few and not enough to create a pattern.
Remember the case in Jasper, TX, where three white men accost a black male on the street for no other reason than he was black, then tie him up and drag him behind their truck, beheading him in teh process? Our country has this particular history, and still has people stuck in that time, so that the country felt a need to go after that particular kind of crime.
You can rest easy, though, that whenever you're in line at the airport, no one will ever assault you just for being who and what you are. And that's all you really care about, I suspect.
