No, just that Europe is more accepting of gay people in general. USA, we are coming around, we are getting there, but anyone can admit that there are more anti-gay bigots in the USA than Europe.
Johnny, I'm not sure about this. I think it depends on the country.
Anyway, I don't see why any tennis player needs to make an announcement about his sexual preference. Just being private about your sex life doesn't mean you are closeted. Not all straight players parade their girlfriends around. Why hound gay players? Just respect everyone for their choices -- well except Tommy Haas or Safin when they were bringing a whole harems to tournaments.
