Whose Business Is It?

I read with interest that there is a bill in Arizona awaiting the governor's signature that basically asks, "Whose Business Is It?"
Some companies want to reserve the right to refuse to do business with certain people due to religious concerns. Think about it. Should a person or business have the right to say, "I don't want to do business with you for any reason?" Should the government have the right to say to a business that you must do business with a person or people you don't wish to be associated with? I say emphatically NO.
Coming from a people who have often times in history been refused service we say screw the business who doesn't want our money. We'll go somewhere else or better yet we'll start our own business and compete with those who don't want our money. Keep the government away. It's none of their business. It's ours.
