Why not? All the commercials show the black guy as the smart one that makes all the right choices, and the white guy as the idiot duffs who can’t do anything right. It’s commercial cuckold on the white boy.
Just imagine the “outrage” if the race roles in those commercials were reversed.
Now, you have to ask - isn’t that, in itself, “racist”?
You can cast a guy one race as buffoonish, but not someone of another.
