In general, I find that women are very accepting and even encouraging when I attempt to emulate a woman. Occasionally, I will encounter a woman who is disgusted by femulation, but most women in the circles I run around in are very accepting.
(Either that or I pass so well that they take me for a real woman, which may be true in a very small minority of cases.)
Anyway, why do women readily accept and even encourage men who femulate?
I have a theory. Most women have a secret: they believe that the female gender is the superior gender. Some women may vocalize that belief, but most do not and let men go on thinking that males are superior.
When a man emulates a woman, women respect a man who has seen the light and wants to switch teams. He may not realize that he is joining the better team, but women appreciate his intentions and some are willing to help him become the best woman he can be.
That is just my theory, but I think it might explain a thing or two.
