I bet it's more psychologically-based than that. From collegiate safe spaces to news media bubbles, to the social networking accounts themselves where nobody honestly follows people or ideas they themselves object to, everybody wants their own gated community/echo chamber.
Personally, as big as I am on free speech and anti-censorship, I don't believe that anybody should be allowed to post pix of minors online under any circumstances, even parents harmlessly to their personal FB profiles. UNLESS it's posting old pix of one's self. Otherwise I feel it betrays the privacy rights of those minors. They may well feel differently when they come of legal age, and by all means they can post whatever they like of themselves after the fact, but in the meantime privacy should be the autoset.
