Okay, so at lunch today, I got in an argument with this arrogant guy, and he said that the more athletic the sport, the better it is, or something like that, but I disagreed with him. According to his definition of a sport, it requires athleticism. Then he used the argument argumentum ad hominem fallacy and accused me for being whimpy. His justification for that at the time was that all I eat at the lunch table is candy

. Then I was like, "what the heck are you talking about?! I did track, I play basketball, and I skateboard!". But he said that I wasn't an athlete because I don't work out in the weight room, and all I do is eat candy, despite the fact that I do participate in sports. Then he used the faulty generalization fallacy and said that I played the piano, so therefore, I'm a whimp. This made me VERY mad, so I raged a whole speech about how physically and mentally demanding it is, and how much harder it is to play the piano than it is to kick a ball around on a field (he plays soccer). Not that I have anything against soccer, I was just trying to explain to him that piano is just as demanding if not more demanding than what most people consider as "sports".
SO... What do you have to say on this topic? Should piano, and other instruments be considered as sports? It fits all of the criteria above. What is athleticism? What's a sport?
I am not saying that piano is a sport by the way.
