I am a frequenter of comic book message boards, those wretched hives of scum and villainy, and I have had male comic fans flat out say they don't like female characters and don't see a real need for superheroines to exist.

It's not exactly a typical position, but it's common enough guys feel free to admit this openly without fear of getting jumped on in mainstream comic spaces. (Or the companion opinion, which is basically that we need girls around for the T&A, but it's silly to want them to do much else.)
