The one reason this weirds me out (without having seen these dolls tbf) is that it was decided something sex-related is too childlike and that somehow makes it illegal apparently? Like, what legal basis is there for it? I have never heard about any law prohibiting 'too childlike' appearance, let alone seeing it apllied.
I mean, have these people seen what's going on in some (not to say many) anime? There are characters being explicitly sexualized, while being canonically underage. How is one thing okay and the other isn't?
Put a 3D behind this and I'm in*
