That's traditional though, and has enough following to keep it. You don't need to watch everything you know
I think the only argument for excluding/including sport should be how widely is it competed at a high level globally. Eg baseball isn't done at a high level by enough countries to include. Possibly cricket and rugby too, although they are widely supported across the commonwealth.
The Olympics is a perfect venue for minority sports to get anmomentnin the spotlight. It should be inclusive. The guy in the 50m pistol probably trains hard too, why kick him out just because its not fashionable?
I wonder if there are restrictions for individual sports from the IOC. Eg in theory the swimming, athletics, rowing and cycling could go on for the entire two weeks as they all have their own dedicated arenas.
I was just replying to the idea that racewalking should be removed because its not the most efficient way of moving.
