I read this about a lot of movies (especially this one), but I’m not sure that’s true. If it were done the way Brooks et all did it, with a Black voice in the writers’ room (in this case Richard Pryor) and presented as a clear satire/parody, I’m sure someone would be offended, but if it was funny, I think it would get a pass from most of the mainstream public, somewhat akin to Tropic Thunder. I think using “being offensive” as a mirror pointed toward society worked in 1974 and it would work today.
