"Imagine, however, if she were a man. Flirtatious, with form fitting clothing that emphasizes secondary sex characteristics, lithe, morally ambiguous, and working as a dashing burglar. Admit it, just contemplating this is making you somewhat uncomfortable, isn't it?"
Damnit, you got me: I'm shuddering with barely contained disgust and sexual insecurity, and now I'm going to go beat up a homosexual to feel better about myself. Jesus, the condescension....
Tone aside, interesting article: given that superhero universe continuity is basically meaningless, I don't see why an established character can't be reborn as someone more diverse (after all, isn't that why we already have Supergirl/woman and Batgirl/woman?). That said, treating the recreation as merely an aesthetic change - "Your favourite hero, now with more melanin/oestrogen!" - is just politically correct pandering. To elaborate, a female Punisher would have to be more than "Grrr, I was raped and now I must kill rapists!"; perhaps Flora Castle is a police officer who is gradually becoming more and more disillusioned by the sheer volume of violent crime perpetrated against women. Perhaps she witnesses one mugging too many and snaps, killing the perpetrator. Perhaps she is protected by the rest of the force against legal repercussion and struggles to come to terms with both the disproportionate punishment and police corruption. Perhaps she decides she can use this corruption to noble purposes and becomes the skulled vigilante we all know and love.
There, I just wrote a new Punisher comic DC: I'll have my millions of dollars now please!
