Your comparison is invalid because nothing that was asked of Jack Phillips to make, went against his beliefs.  He refused to make the cake because of the meaning behind the cake - what the cake was going to be used for.  Its not like Jack told the couple "Hey, ill make you a wedding cake, but I cant make it the exact way you want because its not in my practice".  No.  He flat out said "I will not make a wedding cake for a gay couple".  You cant be fine making 1 wedding cake for a straight couple and then refuse to make the EXACT SAME wedding cake for a gay couple.  THAT is wrong.

Stop with your false comparisons and look at this story for what it really is.  No one was asking this Baker to create anything he had not already made in the past for straight couples.
