"Proponents have argued the bill doesn't target gays and lesbians specifically -- but that it does protect businesses that don't support same-sex marriage from having to provide services for those ceremonies."

There's an easy solution for those business. Just be forward like Chik-fil-a and gays and lesbian will find other places that will accept their business. You don't need a law for this. Seems like these business are more scared of gay and lesbian customers than trying to protect themselves for denying gay and lesbian their service.
You're not going to see anyone sympathize with an athiest who walks into a religious church and suddenly demands he is discriminated because of his views. He doesn't belong there and he knew beforehand he shouldn't be there.
