I think we shouldn't just watch that TV show like a plain sitcom. OK, there are Cavemen, burlesque situations.
But it is a way to see how people respond to someone different. That looks or seems to be different. The question of the embarrasment, of the shame of being seen with someone, going out with someone who's not "of their kind"... stuff like that *do* exist. And if people really see it's stupid, now put a Black man, or an Asian, or a Native, or an Arab, any minority in any country in this world and you'll realize that not only this is stupid, but actually *really* sad.
I hope the show goes on.
