The fact that we are all alike but not the same confers a lot of differential peculiarities on us and the things we do. This can be an asset or liability, depending on what we are looking at or doing but from which perspective and view. Intention often determines approach; motif affects methodology; relationship can easily affect positions. Result matters; giving room for acceptance or rejection, justification or tolerance for the sake of common goal or otherwise.
Our differences can be used to justify or condemn something - and when we are involved, emotions often run amok, putting reasons to test, sometimes sedating it! The vices we see and condemn in others might suddenly become virtues because we are somehow involved or affected. The position we take on a neutral issue might change if someone we know is an interested party. Our reasoning is subject to our degree of partisanship.
