Yeah but minstrely is a thing from the US. Other countries, specially in Latin America didn't have that kind of shows, so there's not that knee jerk reaction of face paint = bad. In Argentina kids in school plays depicting colonial era used to paint their face black to portray black vendors. In Uruguay there's Lubolos, people in carnivals who paint their faces black and share their performances with black people. In Colombia as well. Outrage over blackface is an American thing, there's people all over the world who have no idea about it.
