Mental disorders, like transgenderism and crossdressing, should not be promoted as harmless fun, because they aren't. Back when some movies were made, showing crossing for instance, society wasn't a decade or two away from accepting them like it is now.
Have you never met a woman who was quite masculine? I know women who shave. Ever heard of hirsutism (sp?). There are various disorders in women that can lead to masculine body features. Ever seem the wrestler China, before her surgery? The ugly sister was not, in my opinion, a cross dressed male, just a very, very ugly sister, that was all.
