Given the sordid history of blackface, one would assume the vast majority of Americans disapprove of its use. Unfortunately, that's not the case. 

A recent YouGov survey asked participants whether it is "acceptable or unacceptable for white people to wear black face make up in order to appear as a black person for Halloween." Shockingly, more Americans than not consider it acceptable.

Check out the graph below: 

Unsurprisingly, there are substantial differences according to racial and partisan lines. Republicans find blackface acceptable by a 59-27  margin, while Democrats consider it unacceptable by a margin of 30-53. Moreover, while one in three whites find blackface unacceptable, about seven in 10 (68%) of black people do.

The survey also asked whether or not it is ever acceptable to dress up as a racial or ethnic stereotype for Halloween. The results were similarly split along racial and partisan lines. 

These results are surprising and depressing in their revelations about racism in the U.S.
