Oh dear. There's a difference between people objecting to this because its "sexist" and objecting to this because its demeaning to the character and whats she's supposedly about. Mary Jane dancing around in a mini skirt, or strutting around in her underwear on a catwalk for that matter would actually be more acceptable than this sad and sorry fap-fest, with the caveat that she's actually made to look like a living, breathing, thinking woman and not a horrendously contorted piece of "do me now" that goes against anything constructive and positive the character has built up over the years.
Of course, the sad thing is that nobody would likely ever make
a statue like that, because pretty much everything in the comics industry is pandering to losers in their basement with weird, weird ideas about what is and isn't a respectful and interesting representation of a female comic book character. I don't see that changing any time soon, but that doesn't mean people who object to this kind of thing are going to shut up about it either.
