I suppose the real question is, "Is discriminating against an Event the same as discriminating against a customer?"  This is what the Supreme Court will decide.  I understand both sides of the argument, but I still agree with the baker's right not to make a personalized cake (although my reasons are different than those the baker has stated).  I don't see this as discrimination but as an attempt at coercion to make the baker make a statement in violation of his personal beliefs.  If the baker doesn't want to personally support or endorse a certain type of event, that goes past what he is obligated to do as a business, in my opinion.  Some people might not have a problem making such statements, but he does, and I don't think being in business takes away his right not to make such statements.  In my opinion, designing a "plain" cake was the obvious solution, but I don't know if that solution was offered or not.
