Do you think actors in blackface is offensive?

Oh for god's sake, if a little humor offends the seven voters that said black face is offensive, then you are part of the problem in the world today! Why is it that black folks can poke fun of every race including their own, but no one else is allowed to poke fun at them? Robert Downey Jr. isn't trying to be black he is an Aussie White Dude acting like a black dude. If it's okay for the Wayans to play two retarded white chicks, this by far is A okay. Maybe you should get over yourselves and quit wearing your heart so thin on your sleeve.... If you can't laugh at yourselves once in a while a let others too, it shows how insucure some black folks really are.....Boo hooo.. Robert Downey Jr. is funny in this character......lighten up alrerady geesh!
