Pro athletes compete aggressively with each other but are often friends off the court or field. They know there is a time and place for competition, and because of their circumstances (making millions to do it no matter a win or loss) they can compartmentalize in a healthy way. After all, their literal survival does not depend on defeating their opponent.
Regular Americans, on the other hand, compete aggressively with each other for little gain because we have come to view each other as the enemy rather than the men making us see each other as obstacles to our own survival.
These are overwhelming and exhausting times, and those who choose to defend the criminals and vile men in power over their fellow person, purely for petty and cheap partisan victories, will end up losing the things they think they’re protecting.
