Crazy Crazy Crazy

I was reading this article and it said that "Although federal laws protect people from workplace discrimination on the basis of race, national origin, sex, age, and disability, there is no federal law that specifically outlaws workplace discrimination on the basis of sexual orientation in the private sector." I don't think that is fair at all because discrimination is discrimination and its illegal no matter what and the fact that they don't have a law for that is just down right crazy to me.
