Thinks that you don't like are creepy. Browsing photos on facebook is creepy. Watching anime is creepy. Two males kissing or merely being gay is creepy. Why would anybody give a fuck if you think something is creepy?
No, that's not my argument. The creepiness of these particular photos was his assertion, and I suggested that he interrogate his assertion about why they were creepy (and "wrong") to help see why these photos are in particular problematic.
I was specifically not litigating the enforceability of "creepiness" standards.
For what it's worth: Watching anime isn't creepy. Two males kissing isn't creepy.
