The feeling behind that line was that the Phantom stemmed from a time when it was commonplace for women to lack the same rights alloted to men. It's more him speaking of what people from his time would feel :P

And he's also mocking Elsa's "hard nature" by saying that it is brought about because she isn't in touch with her feminine side.
