@OldiebutGoodie, Wouldn't you agree that petite female actresses playing prepubescent boys in Broadway shows is an anomaly? Finding children of either gender capable of playing the extraordinarily demanding Peter Pan role every night on would be a very tall order indeed.
Not to mention needing to replace them after a growth spurt or voice change.
Yes, society is far more forgiving of women blurring lines that of men. Perhaps that's because more men are insecure about their masculinity than about women's femininity, and are therefore threatened by effeminate men but not masculine women. Also, a lot of men seem to have sexual fantasies involving lesbian scenarios. Not sure why, but they do.
Women have been picking up "male roles" since Adam and Eve left the Garden. Widows had to pick up the slack for their families lest they starve or become charity cases. During wartime women took men's jobs over, and, let's face it, traditional men's apparel (pants and shirts rather than dresses and skirts) are far more practical for everyday living.
The women (and men, for that matter) who I know don't give a hang about whether a woman is more or less feminine or if a man is more or less masculine.
