Actually there is a vast difference between legal and illegal. It's not an either-or situation, so that is why we have the courts.

You might prefer it if the world would resolve itself into simple b&w to take out the nuances that make it so bothersome to you, but most of us appreciate the rich and intricate nature of life.

Anyway, the point is that legal or illegal is not a label that you apply to a human being, it is a state of being that is conditioned on a legal framework and determined by qualified professionals. 

I could be wrong, but I don't get the impression you've passed the bar.
