On the one hand I am completely sympathetic with people with legitimate religious reasons to not participate in certain activities. On the other hand you don't want businesses to be able to willy nilly discriminate against someone based on their race, sexual orientation, etc. and be able to use religious exemption laws So how do you balance legitimate religious objections with equal protection? Not an easy thing to do and I suspect most of the legislation being proposed will never pass a court challenge.
What bothers me is the people who go out of their way to creat a case against someone. If there was some bakery that objected to baking cakes for a Catholic wedding I am not going to go out of my way to make a federal case out of it. I will just take my business somewhere else. Many of these groups do the opposite. They call around to find some business that doesn't want their business and then get their 15 minutes of fame. To me that is reprehensible. The gay mafia is famous for this tactic.
