I think the Cowboys are one of only two teams in all of sports that engender love and hate to that extreme. The other is the Yankees. You love the Yankees or you hate the Yankees.
Sport is the bloom and glow of a perfect health. The great will not condescend to take anything seriously; all must be as gay as the song of a canary, though it were the building of cities, or the eradication of old and foolish churches and nations, which have cumbered the earth long thousands of years.
Also our fellow competitors, who are indeed the people just mentioned - we do not compete with men who lived a hundred centuries ago, or those yet not born, or the dead, or those who dwell near the Pillars of Hercules, or those whom, in our opinion or that of others, we take to be far below us or far above us. So too we compete with those who follow the same ends as ourselves; we compete with our rivals in sport or in love, and generally with those who are after the same things; and it is therefore these whom we are bound to envy beyond all others. Hence the saying.
