Can you help me out here, and find me some links? Google and Wiki results are leaving me dry, and that includes keyword of "bowls" as well. There are world championships, but I can't find anything about Olympic lawn bowling.
I'm not sure what era you are implying with Christ being a cowboy, but if it's the original Greek event, that was as much music and art as it was sport, rendering just about anything we argue as moot.
This is simply a bad argument. If a joke instead, it's also bad. Lastly, you don't know that, anyways.
Semantics? Everything, and I mean everything, can be considered as an art. Some things are just more artistic than others, IMO.
Likewise, anything that is a competition can be perceived as a sport. Some things are just more of a sport than others.
For instance, baseball is one of my favorite sports, but the candidates for competition are firstly chosen by their ability to hit or pitch. Not so much in baserunning, arm strength (for position players), or defense. There are many that can do the latter, but few that can do the former. Hitting is considered by many to be the hardest thing to do in sports. Yet, a batter might have a bloop single, stand up double, a walk, and a couple of strikeouts, and hardly break a sweat during the game. This position player might have nary a ball hit to him. Therefore, I consider it less of an athletic sport than the other major US sports, such as football, basketball, or hockey.
To answer the question, by the simple act of competition is curling a sport. The same goes for shuffleboard, darts, bumper pool, bags, bocce, etc. None of these "sports", however, are worthy of being an Olympic event, IMO.
Otherwise, it looks like a very fun game. Some of the female competitors are attractive. I do wish, at least where I am, that there wasn't so much focused coverage on curling, as I'd really prefer to watch other events that I consider to be more of a sport than the sport of curling.
