I think the point that has sailed over your head <thinks... that means he's underwater, scuba-diving, perhaps>, is that there is joy in life, and value in games, that do not fit your world view. Just because you or your kith and kin don't play a certain game, or because you think it's a parlour game, does not mean that it is so. You were horrified to think that beach volleyball could be considered other than a serious endeavour, but are happy to blithely dismiss table tennis as if it were some kind of kids' game. Millions of people, indeed hundreds of millions, disagree with you.
Table tennis is not a major US sport, it appears. It has fans and detractors. I don't like the sport to watch but I respect immensely the incredible skills of its best competitors. You and some others, Chris, seem instead to speak from a position of callous ignorance about the sport--not knowing, not caring to know--and then affect a wounded air when people do the same to your favoured sport. You can criticise a sport, of course: just do a better job and recognise the inconsistency of your stance.
For mine, I think table tennis is a worthy Olympic sport, whereas I have my doubts about beach volleyball. It is not about whether I find each sport entertaining (neither is, in my opinion), but simply because one is much more widely played than the other. The debate about whether beach volleyball ought to monopolise TV screen time is a different one, and then aesthetics (of both sport and, inevitably, its competitors) might more validly be discussed.
That is why the references to rugby instead of American football were made. (Not because either is an Olympic sport; everyone knows that neither of them is.) It is simply that different sports have different perceptions in different countries. American football is played in Australia, laughingly badly by US professional standards. I would be foolish to judge Brett Favre or Emmett Smith or whoever by the sport as it is played in Australia; I don't. Likewise, what I think of as a turgid, 3-hour advertisement collection interposed by occasionally riveting play, most Americans enjoy immensely. You doubtless wouldn't like or couldn't understand rugby (along with, I must say, most Australians). I have another view. It is not God's truth, though, it's just my opinion, informed no doubt by my country of origin.
Your jokes and arguments, if they may generously be termed such, are insular and parochial. Expand your horizons a little.
