In what specific, concrete ways does it not work out the way you think it is intended?

A trivial example is that a business owner cannot be vocally anti-same sex marriage, because if she is, and a gay employee is fired for a "legitimate" reason, her behavior will go a long way towards convincing a jury.
Where this is going is why we are expanding the number of protected classes over time is that the real "intended result" is that you should not suffer at work for attributes that have nothing specifically to do with the job you are hired for.
