Roger's black face episode -
I love this show! Still not fully recovered since its end.
In the current climate, I hope that no one decides to tamper with or delete the episode where Roger wears black face. Putting this in the context of that era, this sort of thing was not frowned up. Most people present are either entertained or remain silent. Don Draper is disgusted by it and wants to leave.
We have already been shown that Roger is a racist, he is typical of the white male who enjoys his privilege. His outburst at the Japanese executives and his comments when Don hires a black receptionist reveal his attitude towards diversity and tolerance. He is not a forward thinker.
