Wrestling was dropped from the Olympics because
it didn't have friends in the right places. That's it. End of line, as the Master Control Program would say. And this: "FILA didn't think its sport was at risk, so it waged virtually no campaign to save itself." Wrestling--perhaps THE sport that harkens back to the ancient Olympic times, when the Greeks famously wrassled sans any clothing--should never, even have to justify itself to anyone, and definitely not to a pack of loathsome IOC aristocrats. What bullshit.
...you can also see this as the expression of the IOC's anti-Americanism, as we have the all-time medal count in wrestling and the last two sports cut--baseball and softball--were also American as spam musubi, but that's more of a reach, in my opinion.
