So far, no harm, no foul. It may be irritating that your political opponents choose to make your personal political predilections the basis of a crushing economic attack. But it's their right.
But now let's say your political opponents are in government. And let's say they use the power of their office to shut down your business -- not because you violated any law or broke any regulation, but because they don't like your position on traditional marriage.
This would be fascism.
