You apparently have a very narrow viewpoint then. It's like you want to believe the motive is discrimination so it's all couched in discrimination. Most people just view it as a oddity...it's not some sort of religious issue like gay marriage.
Can you tell me what someone isn't getting that someone else gets to do? I don't see it. If the bathrooms/lockerooms are essentially the same as even argued by people who hate the bill (the why does it matter argument), then everyone is using the same facilities. No one is being denied a thing of substance. The black bathroom issue, often used as an analogy, doesn't really fly because back then it was outhouse/none vs modern facilities with running water, etc. Gay marriage was spousal rights, benefits, court rights, etc. Here?
