People like to work, live, trade with and socialize with like-minded people. That's why we're here on DU, as opposed to hanging out at Free Republic. It's just the way people are. It's natural. We are tribal animals. It's also natural as "tribes" grow and become more powerful, they discover they have the ability to force others think and live as they do. This is where the danger lies. It is repeated throughout history. So, I understand what you are saying about thinking of buying blue differently, were they to gain an unfair advantage, but the very human tendency towards this type of behavior is the same, at it's seed, in all facets of our existence.
