Why do you think that is? Are there other social media where people say smart things instead? My sister uses Snapchat, maybe it's that one.>>4658
Anyway, I will argue against my own argument. I think most agree that how someone dresses, for example, is not to blame for sexual assault in adults. And I think we can also say that if a boy cross-dresses, and an adult who sees it feels it is sexual and acts inappropriately, it's fully the fault of the adult, not the dress or anyone who might have permitted a boy to wear a dress. In broader terms, to admit that a child can be sexualized is to legitimize the perspective of people capable of being sexually attracted to children -- not a particularly sturdy rhetorical plank to stand on.
Of course, then the count-counter argument might be -- yes, yes, we oughtn't change just to accommodate a hated minority, but you still want to play it safe, don't you? Lock the doors, put up fences, and encourage the least sexualizible identities in children.
