I personally believe that sexual discrimination should be completely legal. That is, if you don't like someone for being gay, you don't have to hire them. Why? Because being gay, at root, is an ACTION. Sure, you might be gay because you were born that way, but unless you act upon it openly then nobody will know. Being black/female/male/white is what you are and can't be helped (nor should it). Once you start making laws prohibiting discrimination for actions, you open the door for all kinds of nonsense.
Lets take religion, for example. Imagine having to put up with some idiot at work who, as part of their "religion", chooses to wear a shirt to their customer service job reading "I hate you and I wish you were on fire." Because the Constitution doesn't involve itself in the establishment of religion, or legitimization of religion (this is a religion, that isn't, etc.), any law by the government protecting people from religious discrimination would have to protect the idiot at work and his stupid shirt.
