I've heard it said that in Europe blackface doesn't carry the same negative connotations as here in the States because there isn't such a history of rabid racism/slavery/minstrel shows and such.
Not that it's right, but just for some perspective before any attacks.
The reason blackface carries such a negative connotation in America is because of minstrel shows, which is almost exclusively an American form of entertainment. So no, blackface in Europe is not considered as "wrong" as it is in the US.
As Mr. Nowak says, it doesn't make it right, but that's why it still happens from time to time there. I remember someone posted a clip from a few years back of a production of Ragtime where someone was in blackface.
"Carson has combined his passion for helping children with his love for one of Cincinnati's favorite past times - cornhole - to create a unique and exciting event perfect for a corporate outing, entertaining clients or family fun."
WOW. So I was going to say something about it being the 20s and maybe they were going with the whole "blackface" look as it was acceptable at the time but alas no it was not what I thought of as blackface. #yikes
"Whenever I get gloomy with the state of the world, I think about the arrivals gate at Heathrow Airport. General opinion's starting to make out that we live in a world of hatred and greed, but I don't see that. It seems to me that love is everywhere. Often it's not particularly dignified or newsworthy, but it's always there - fathers and sons, mothers and daughters, husbands and wives, boyfriends, girlfriends, old friends. When the planes hit the Twin Towers, as far as I know none of the phone calls from the people on board were messages of hate or revenge - they were all messages of love. If you look for it, I've got a sneaky feeling you'll find that love actually is all around."
