If America was comprised of all liberals, there would be no sporting events!
Sports are about achieving greatness, working hard, being excellent, separating "great" from mediocre. Liberal sporting events would mandate that anyone who wanted to play, could. Liberal sports would be about "fairness," meaning that everyone would get a medal, a trophy, and any monetary prizes would all be distributed equally, among all the teams, all the players. (Naturally, those prizes would be taxed at upwards of 60% to federal, state, and local governments.) Liberal sports' teams would wear uniforms colored in soft pastels, with lots of padding...nothing to intimidating.
Liberal sports would be the most boring thing in the world, and could never commercially sustain themselves. In short, they would require government subsidies.
