Golf

STILL not a sport.

If you define people who play sports as athletes.
If you imagine someone who says they are "into sports".
Better yet, if someone tells you "I'm an athlete."

NONE of the next words out of their mouth is "golf".

Golf never has been a sport. There was never an ancient form of golf where one golfer tackled another. Golfers never succumbed to exhaustion (related to golf). One town's golfer never faced down another town's golfer for the pride of the township.
