When did a white guy wearing black makeup became unacceptable?

I don’t know about any criticism of that Patrick Stewart Othello. I’m not sure why there would have been any, though. He wasn’t pretending to be black. They cast the play in a way that allowed a white guy to play Othello without makeup and maintaing his status as an outsider.

Then-House Minority Leader Bob Michel (R-Ill.) took some heat in 1988 when he fondly recalled the minstrel shows of his youth: Jet - Google Books

He was the dude dressed as a dude disguised as another dude!

Anyway, ahem…
The Minstrel Show to the past has gone
His glory days are all behind him.
His racist charms he hath girded on.
Lest he smiles we shall not find him.

And so forth.

I remember the first time I saw Darrell Hammond do Jesse Jackson on SNL I kinda caught my breath and wondered if this was “OK” or not. Was sorta surprised when it turned out to be a “no biggie” thing. Jackson was one of Hammond’s weaker bits and it didn’t get much play anyhow.

What does IEHO mean? Neither Google’s define function nor the urban dictionary know.

That’s because it’s not a standard abbreviation, but a riff on IMHO: In Everybody’s Humble Opinion

La Raza, the HIspanic cultural identity, describes people of a mixture of white, African and indiginous American bloodlines. Armisen, who likely has some Black ancestry (his mother is Venezuelan), has more “right” to play Obama than, say, a young Chevy Chase would. And he resembles and impersonates the man a lot more/ better than Kenan Thompson or Jay Pharaoh, which trumps most other considerations.

The show was Gimme A Break, and the kid was Joey Lawrence, who was basically the Nell Carter character’s adopted son, not a son in the family she was working for.

In one of the Little House books, Laura Ingalls Wilder described her father being in a minstrel show.

I kept waiting for Michael Landon to pull it off on the TV show, but it never happened.
