Well, in that case, we should also expect that people who write about how they teach their children about AIDS or avoiding pregnancy should be censured, because that is certainly "private and intimate". Instead, public policy is that this sort of education should be made as public as possible, even made mandatory in the public schools.
Sexual health is not something we should be avoiding talking about, and "sexting" can be devastating to young people when things go wrong. I don't think that there is anything more inappropriate about writing, "I told my child not to send nude pictures to their friends," than "I told my child to always practice 'no glove, no love'".
To the bold: absolutely! That was exactly what I meant - write about it all you want, as a mother or father, but do it anonymously!
Surely parents shouldn't post in their own name, publically, about their very intimate conversations with their children?
That belongs in the privacy of their own houses!
It is one thing to be taught about these things at school, in the presence of your peers.
But what is said about private lives, between you and your father and mother, do you really want to see that out on the internet with your name on it, as a teen? I don't think so!
Do you really think it is acceptable for a parent to make such things public? Non-anonymously?

If I was the child of a parent who did that, I would never discuss anything intimate with my parents again!
