On the one hand, the baker could have refused and stated that he's got other stuff and can't take orders at the moment - instead he had to go and say that he's not taking their business because he disapproves of their lifestyle.

The gay couple could have just went to a different baker and just let the baker suffer loss of future business, but no - they had to drag the courts into it.

Way I see it, both sides wanted to get back at the other for not accepting their beliefs.
