Ironically, everybody is part of a minority, it's just a matter of context. In San Francisco and many liberally-oriented cities, one of the minorities is Republicans. These Republicans have virtually no political representation at the municipal level. In a winner take all situation, the losing minority is subsumed by the deluge of the winning majority, which is really a collection of winning minorities. It's a very tribal affair.
Losers learn they are marginal in a winner take all society.
No one likes to lose all the time, or even most of the time. Losing is uncomfortable, unprofitable, unhealthy, maybe even dangerous. No, winning is much better. We learn that from the earliest of ages, we have that drummed into our heads. We want to win real bad, and so we learn how to do that as best we can.
