The thing is - the Jamaican characters in Cool Runnings were not, as far as I can remember...jet black golliwogs.
A closer representation of what a black man looks like is the make up that Robert Downey Jnr wore in 'Tropic Thunder' (for which he earned an Oscar nomination).
There's a world of difference between that and 'blacking up' like a minstrel.
It's no where
near as bad as Mickey Rooney in Breakfast at Tiffany's, but it's still pretty childish.
Also, let's not pretend that it's only black people who get offended. I recall quite a few people were upset at Little Britain's Mrs Emery.
