The medical profession used to be totally male-dominated. That didn’t stop women from becoming doctors in droves despite all the discrimination and outright bullying they faced. Now women dominate many of the medical specialities.

I think this is different. I think becoming a film director is simply not a viable career path for 99% of all people who attempt it, regardless of gender. This is very much distinct from both acting and music as careers (there are countless moderately successful small-time actors and musicians but almost no small-time film directors).
