What it would be doing is changing a fundamental aspect of a classic character. It's like casting Superman as black. Would you really get cries of "racist" when people protest to a black superman? This kind of PC bullshit annoys me a lot. If a female actor wanted the role of a popular male character (lets say, Batman, Superman, or even Harry Potter), would we deem it sexism if it were denied? We wouldn't, or at least we shouldn't.
Equal opportunity is a good thing, but you can't expect someone incapable of fulfilling a particular role to fulfil a particular role.
