No evidence shows this was a setup by Phillips so he could put gays in their place. He didn't open his bakery 23 years ago hoping gays would someday gain the right to marry and then he could refuse to sell them cake, win the court case, and put up a sign saying "No gays allowed." 

On the other hand, gays have gained power and now want to impose their beliefs on everyone: Bake us a wedding cake or else. It's legal force used to impose the new belief system and destroy the old system. A lot of people still believe marriage is between a man and a woman; these people must embrace the new definition or be put out of business.

The gay couple, by the way, got a free cake from a bakery about a block away. But they still want Phillips shut down. 

So, yes, this is all about power: the power of gays to impose their beliefs on everyone. I hope the SC imposes limits on that power.
