I have the opposite reaction when I see these memes. To me it’s a reminder of how inclusive some of my favorite nerdy communities are, on top of being a fun little in-joke like any meme should be. And I’m an old beardy middle aged dad too for whatever that’s worth.

However, that doesn’t mean the image itself is innocent or appropriate for most audiences. I’m not going to be asking the family’s opinion on this one, lol. But I don’t see it as a manga fetish thing at all. More empowerment than exploitation for the owners of the legs shown.
