Gays are not forcing anyone to do anything. If you feel you cannot serve gays (I use the term "you" generally, not YOU in particular

), and cannot follow your state's anti-discrimination SECULAR laws which are based on equality in business dealings, then you do not have to go into business.
People can feel disgusted or any other way they happen to feel, but that does not give them any right to single out any particular group of tax-paying American citizens who contribute to our economy. It is bad and STUPID business for any state to adopt. That is why it is illegal in our country. We are not Iran and our laws do not support any particular theology, thankfully.
Instead of feeling "slighted" it is important to look at the bigger picture and why it is important to keep religious beliefs out of government and business. You are still free to practice any religion of your choosing and perform your religious customs/ceremonies/whatever.
