Saw this film for a second time yesterday and it was great being able to catch things that "didn't click" on the first viewing, particularly the family and the silent auction. How the Black people who had their brains swapped acted and knowing that they were really White people in Black people's bodies made their actions make more sense/click much faster. Example, when the Asian male auctioneer asked how things were as a Black man and Chris passed the question back to the other "Black guy" there, it made the scene more messed up knowing that that was a White guy giving the "there's no difference" response.
One thing that I've been thinking about after seeing the film a second time is Georgina/the Grandma, the one Black woman victim we see. From the silent auction/etc... and looking at things from the perspectives of the auctioneers, their main motivations on a basic level are getting "new bodies" due to growing old/not being as physically fit as their victims. But as Chris asked the blind artist, "Why Black people"? Again from the auctioneer's perspective, why not get bodies that look/feel like what you're used to? Now of course, the film explains this well in regards to many of the auctioneers wanting Black male bodies due stereotypes like "superior strength", "being great in bed" from the auctioneer wives, etc... with the father/grandfather being the worst of the bunch in regards to thinking they are doing a "service" to their victims by putting their "genes" to better use.
But none of these stereotypes "work" for the Grandma. There's no stereotype motivations for her wanting a Black woman's body shown or discussed in the film (Ex: Golf Swing, Running abilities, etc...), just us seeing her focus on her looks in the mirror. As discussed in the thread, there is the "no one looks for Black victims" angle (although this could also work for any non-White US ethnic group), the film mentions "Black people being in", and of course for the purpose of the film Georgina had to be Black, but I would have liked to see some Black woman stereotypes explored from the Grandmother's perspective.
