You can argue it's weird to debate sex online, I just think that stating that nobody should talk about sex online, because a minor might see it or wade in to the discourse, has the spirit of Mary Whitehouse in it.

While I'm on your soapbox about it, parent your own damn kids, I'm not going to stop saying fuck & announce how queer & gross I am whenever I please because you can't figure out how to turn on the safe search. It's not my problem that little Timmy was left unattended in the open forum by you.

Yeah that argument silly. I mean there's an argument to be made that people online should be more selective to WHO they will argue with about sex so they don't end up looking like a creep if it turns out the person arguing with them is like 14 but that's a totally different discussion.
