my position is more to get one to think outside the social norms than anything else. we all exist on what we hold to be true for us, it is our moral compass, so to speak. i would be willing to bet that you have previously held a belief that you no longer believe to be so. that is a byproduct of your evolution in life and is based upon your beliefs. as such, you have held contradictions to your current positions.
the issue of socially accepted norms is required for the advancement of a society, as a whole.
