Call me whatever names you wish, but I think this is a much better (and healthier) attitude than “anyone under 18 should never be allowed to see any sexual imagery ever”
(For reference: this was at the Tom of Finland exhibition, containing actual, queer, kinky af pornography. There were definitely some young people there, perhaps in their late teens. There was even a parent with their baby who was probably too young to understand anything at all. And guess what, all those people are probably going to be fine.)
[ID: a sign saying “Please note: there is no age limit, but the exhibition is not recommended for children due to the explicit sexual imagery it contains. Parental or guardian discretion is advised.”]
