I just took a look at the photo of the story above. The first thing that really struck me is their arms - very sinewy -and the second thing wasa their ribs showing through the leotard. The female body just has more body fat and the female form is more 'rounded' and softer looking. So no, unless in full costume I wouldn't be sure (i think the face is of a beautiful male or 'handsome' woman').
Taking parts from the women? No that's not on really is it? You aren't hearing howls of protest like you do when an actor plays a part that is not the same as their own sexuality, race, gender bla bla bla.
