I've seen some weird defences of the IWTV writers room couching in 'erasing the contributions of the non-white writers' type arguments and I just want to use this helpful breakdown of the writers to take it a bit further.
I also want to start off referencing a quote that screenwriter-director Nida Manzoor made where she talked about being in white-dominated writers rooms where she felt she was there to just sign-off on what they were writing. And what a difference it was when she was able to set up her own writers room, especially in season 2 of We Are Lady Parts, where every writer was a Muslim woman.
If you're not familiar with how writers rooms work, you might think every episode is created by the person credited with the script. (Flashback to the Buffy fandom where Marti Nixon was blamed for every single thing in the Joss Whedon is God days.) But the whole point of a writers room is that everyone breaks the episode beats together, and it is headed by the showrunners.
Now let's look at the racial breakdown of that IWTV writers room again
1x01 - Rolin Jones (white)
1x02 - Jonathan Ceniceroz & Dave Harris (Latino and Black)
1x03 - Rolin Jones & Hannah Moscovitch (white and white)
1x04 - Eleanor Burgess (white)
1x05 - Hannah Moscovitch (white)
1x06 - Coline Abert (white)
1x07 - Rolin Jones & Ben Philippe (white and Black)
2x01: Hannah Moscovitch (white)
2x02: Jonathan Ceniceroz & Shane Munson (Latino and white)
2x03: Heather Bellson (white)
2x04: Coline Abert & A. Zell Williams (white and Black)
2x05: Jonathan Ceniceroz & Hannah Moscovitch (Latino and white)
2x06: Hannah Moscovitch & Shane Munson (white and white)
2x07: Kevin Hanna & Rolin Jones (white and white)
2x08: Rolin Jones (white)
3x01: Rolin Jones & Hannah Moscovitch (white and white)
3x02: Jonathan Ceniceroz & Kevin Hanna (Latino and white)
3x03: Anusree Roy (Indian-Canadian)
3x04: Jonathan Ceniceroz (Latino)
3x05: Hannah Moscovitch & Daniel Hart (white and white)
3x06: Ryan Kattner & Kevin Hanna (Wasian and white)
3x07: Hannah Moscovitch (white)
So - not a single Black writer has been given solo credit on any episode. None of them have ever made it beyond one season into a writers room. Of the non-Black writers of colour, Jonathan Ceniceroz is the only one who has written for all 3 seasons, and he only got solo credit for one episode this season. Anusree Roy being the only other non-white writer to get a solo credit. Ryan Kattner probably contributed most to song lyrics, since he's a musician who is also acting in the show.
The show runners and producers are all white.
This is a white-dominated writers room, and this is a show where white writers set the tone of how race and racism will be addressed in the scripts. And if you have followed some of the things Hannah and Rolin have said in interviews, you should know that neither is to be trusted when it comes to racial awareness.
