This is not the first offensive display — and probably not even the worst. I pretend to no authority but have seen enough to know that MTV videos often resemble soft-porn mini-movies. Children marinating in a culture of online porn, sexting, rainbow parties and worse have little experience with other ways of relating emotionally.
Someone actually pretending to authority, I suppose, would have known that MTV doesn’t show videos and hasn’t for years. (Not that their “reality” shows are any less noxious.) And has anyone ever actually attended a rainbow party? Snopes seems skeptical.
