No one knows who Batman is (except for people who've read the comic books or seen the movie or the tv show) -- so why couldn't anyone be Batman? He has no superpowers; he's just a guy who dresses up in a costume and fights for justice. If someone else did that how could anyone tell him from the real Batman? Wouldn't he be Batman, too, just as real as the real Batman? In fact, why would he need to wear a costume? Why shouldn't he fight for justice in whatever clothes he feels comfortable in? Why can't we all do that? We can all be Batmen and Batwomen!
With all of us prowling the streets disguised in ordinary clothes, injustice won't have a chance!
