A sport is any competitive activity done for the enjoyment of competition. Those demanding it require grand physical activity are looking more for the term 'athletics'. You can play any game, phyiscal or no, is sport. You can have a debate in sport. You can play chess as sport. Why do you feel the dexterity and concentration to fire a bow better than your competitors is sporting, but the dexterity and concentration to win EVO is not? By attempting to say activities played in sport are not sports because they don't involve catching a ball, or because they're not entertaining spectator sports, it's only because that's the type of sport you grew up with.
