History would disagree. We're still living in a society shaped by Quaker beliefs about sex, children, and the human body in general.
It's telling that the article didn't interview anyone with expertise on the history of sex or people who study sex professionally (as academic scientists and researchers). Porn is definitely more easily viewed than ever before and that may be shaping kids views of sexuality but how is that shaping adult's views of sexuality? Why are kids special?
I'll tell you why kids are special: It's because it has become acceptable to assume that kids being exposed to sex of any kind is somehow "bad". Nowhere in the article do they talk about why it is that kids aren't learning about healthy sexual relationships: Because we hide that from them.
No one wants to talk to their kids about sex but if there's one thing you should tell kids (not just your own!) about porn it's this: It's fake
