I agree that this is not a good thing. No one should be fired for having controversial opinions or even being accused of a crime. I believe that "morality clause"-style firings should only occur when a) the employer is among the aggrieved parties (e.g., the employer accuses the employee of theft or other unlawful conduct); or b) the employee is convicted in a criminal court.

I've had way too much of people getting fired for petty personal disagreements or baseless accusations.
