The main point here is the notion of protected class. http://en.wikipedia.org/wiki/Protected_class In the United States protected classes are predominately traits upon which the individual has no control over (the notable exception being religion, pregnancy, and veteran status which are present because of constitutional and social value reasoning). Because of this line of logic egalitarians in this country support moving sexual preference as a protected class. Holding opinions (for whatever reason, you don't get to hide behind religion on that one) is on you and if that causes your employer to look bad or runs against what they stand for it is perfectly reasonable to expect to be let go.
