An ad on TV for the PGA says that the mission of its members is to "spread the game of golf to everyone, everywhere."
Why? Should the world become entirely wrapped in golf courses so that we can accommodate 7 billion people teeing off at once?
If someone believes in, say, Christianity, or libertarianism, or communism, I can see why they would want everyone else to believe in it as well: they think the world would be a better place if everyone did. But does anyone "believe" in golf in this way? The world would be a better place if only everyone played golf?
