Its not productive or proper to call Americans, Dominicans or Newfies dumb(I was just f***ing with you on that. I'm originally from NS too). Its especially not right for people of supposed influence who speak to millions of people, because it perpetuates stereotypes. When Don Imus called the Rutgers girls bball team "nappy-headed hos" people were rightly offended.
I actually don't hear people of influence or leaders calling Americans dumb, at least not openly. It would be equally as ignorant. Cowherd's comments were not well chosen and Bautista's statement in response to his clarification was measured and appropriate.
If Dominicans want to poke fun or judge their education system etc that's one thing, but let them do it.
