I don't know if there should ultimately be any protected classes in our system. The argument is that classes need these protection until such a time that the barriers that bias imposes are ground down by public policy and we live in a not racist sexist, biased society. I fully accept that government officials should never act in a biased way toward a class of people and that institutions that receive government money should not act with bias toward any class of people that would otherwise appropriately receive services from those people.

I have a much harder time with the idea that a cake decorator is required by law to make a cake for a gay couple's wedding if they don't want to. Criminalization of personal biases seems to be basically un-American to me.

Of course some homosexuality is a decision, the ancient greeks proved that. Homosexuality, namely mentor relations of a sexual nature between boys and men was the norm in their culture, it's not today, obviously a cultural not genetic relation. I am willing to see if some homosexuality is originates from a non cultural or personal choice origin. Science is slow and we haven't been good at it for very long.

Bigotry toward homosexuals is wrong if you pretend to be a Christian or a Patriot. Persuit of happyness seems to me to include letting consenting adults do whatever they like as long as it isn't harming others. Christian based bigotry toward homosexuality is something I don't really want to get into aside from I am pretty confident how Christ would treat homosexuals regardless of weather he thought they were on the right path or not.

Homosexuals are pretty much indifferentiable from all other people. Bigotry against them, if you believe that people should be allowed to follow their own happiness and that all people should be treated with dignity and respect, is stupid and wrong. Being stupid and wrong is a right that we as americans have, I guess it's part of the cost/benefit of freedom.
