It's hard for you to grasp.  I am not in favor of any kind of discrimination based on sexual orientation or any other reason.  We just differ on what we think constitutes discrimination.  I don't believe that an Event has the same protection as a Person.  A person just IS, but an Event is a Choice.  I understand and believe that a person should be able to abstain from any appearance of supporting a particular event with their personal expression, artwork, etc. even when I think they're wrong for doing so.  I don't agree with the baker's reasoning or position in this case, but I do believe that he has the right to act the way that he did.
