It's almost as dumb as renaming lake Ontario to Lake America to "punish" Canada (presumably because it shares its name with the province of Ontario), when that lake has had its name since the 1600's (before the USA or Canada even existed) and is based on a Native American Iroquoian word. And the province of Ontario was named after the lake, not the other way around.
But at least with South Park, I can understand their motivation.
