Every show has to let ignorant activist writers use some or all of the characters as megaphones to lecture the audience. Activists only write themselves, they can't construct independent characters.
The Monica character in this episode was used to that effect in cringe-tacular fashion. It was like the wet dream of a frustrated twitter user creating fan fiction where she puts the white chud in their place and everyone claps, except this would only happen in their head and when you try to make it reality, it looks exactly as bad as it ended up being.
Not to mention it was nothing buy lies and hypocrisy and brings down the show to a level that will keep it under the greats like Breaking Bad which never succumbed to the low hanging fruit of using its story to lecture the audience rather than creating a story that had no intent to use its characters as a vehicle to "educate/lecture" the audience behind the veil of a TV show's script.
The show has its good parts, but then it has parts like this with increasing frequency which feels like a completely different show. Is this from Taylor or another director or writer thats trying to fill in their part? If so, they've done nothing but drag the show down. People don't know how to write a show anymore, they only know how to convert their bitter tweets into a script and thats what's happening these days.
