Is Batman gay? DC Comics refuses to comment, or indeed, to allow anyone to do so using
its trademarks or artwork. Though the first allegations of this (from before
the high-camp Batman TV series of the '60s) did prompt the invention of a
nuclear "bat-family" with female members to dispell the allegations of
homoeroticism (back then, commercially damning, and not a niche marketing
opportunity).
(Copyright laws require permission from publishers to quote images, which has crippled academic criticism of comics. Though I seem to recall that Ariel
Dorfman's scathing Marxist critique of Disney comics, How To Read Donald
Duck, quoted quite a few strips; I find it hard to imagine Disney,
with their authoritarian, McCarthyite culture, signing off on something
like that.
