Allowing a business to use Religion as an excuse not to serve someone is the ultimate slippery slope to allowing a business owner to discriminate against anyone, for nearly any reason.  How is refusing to serve a gay couple now any different than the racists that refused to serve blacks or mixed raced marriages back in the 40's and 50's?  The answer - its not.  Its discrimination painted with a different brush and people are using the Bible as their shield.

And to be clear - no one in this case was forcing this baker to do anything different than what he already did for hundreds/thousands of customers before.  No one asked him to cater the wedding or write something on the cake that he found offensive.  It was simply the fact that a cake he was making was going to be used in a gay wedding.  Thats it.  So, based on that standard, could the owner of Hobby Lobby come out and say they no longer will sell any of their products to anyone who has had an abortion?  How is that any different?
