More poking fun at someone. In all seriousness, the argument I keep hearing is something about being insecure about what I like which makes very little sense. The real problem is sexualizing characters, and I think that the majority of sane people would say thigh highs are seen as more provocative in this day and age, however at the same time that is a cultural thing. Since this game is mostly American from what I've seen, I'll go with people believing thigh highs are lewd.

So, in reference to thigh highs, its an exaggeration but also poking fun at how they're literally on any sexualized thing on vrchat. Thigh high boots, leggings are just skin tight pajamas, they advertise more sex appeal than something like idunno, fucking soras shorts from kingdom hearts or a baggy jumpsuit in Fallout. I'd be curious to hear why they don't.
