Very few cases.
But we all know regardless of what laws are in place deep inside we all make personal judgments upon people because of their appearance, and it is wrong.
No it isn't.
People's appearance can say much about them, and the things that it says often are legitimate reasons for making judgements.
I agree with you that a persons appearance can say much about a person, however does it tell you if someone is honest or loyal, that they are of good character....yes and no. Many people dress the outside up but they are filthy inside.
