Talking about racial issues or LGBT issues in the episode is one thing, but I don't think "it's only an hour-long episode for normal people!" is a very good excuse(?? if it needs one) that the show only interviewed white people. "Whoops, we didn't even think about it" is a more sympathetic, believable defense. Or, "only white people responded to the casting call/equivalent".
