in your example, both ppl are biased, but one is a hypocrite.  The closest you will ever come to not being biased is impartiality.  That is, to have no stake in either outcome.  Jay no offense, you are biased and you want rules that protect you.  i compliment your effort to try to be impartial.  Just dont let it blind you from the truth.

No offense taken.  Im asking because i dont see why one is allowed but not the other though.  It actually has been a while since anybody has called me biased (unless im forgetting) so this isnt really about me.

From what I can see you are an xbox fan, but also seems to a rational one and I respect that. (Just from what I've observed casually, I could be wrong)
