Yes, there are some great players from Japan, but not half the league's hitters like Blacks in the 50s, 60s and 70s. Anyway, Japan is not America. There are professional baseball leagues in a lot of different countries. Are we supposed to recognize all of them as Major Leagues?
Americans were banned from the American Major League, so they started their own American major league and now it is finally being recognized as such. I don't really understand why this is a problem for some people.
