A Swiss soccer player has just been sent home for tweeting a marginally racist message about the South Korean soccer team. (By the way, we are reaching the point where the twin pillars of youth communication in the Internet age -- snarkiness and political correctness -- are coming almost daily into conflict in the ethersphere of Twitter and Facebook. You can't be edgy and transgressive and, at the same time, observe all of the proprieties modern liberalism demands.)
Earlier, a Greek athlete was sent home for a marginally racist tweet too.
Meanwhile, the Lebanese judo team can, with impunity, refuse to practice in the same gym with Israelis. And the IOC refuses to give a moment of silence in memory of the Israeli athletes slain at the 1972 Olympics.
I'd say "Shame!" but no one would listen.
