If women see STEM positions as inhospitable working environments, online or otherwise, then it is our responsibility to work toward creating inclusive environments conducive to work by all. YouTube is only part of a much larger struggle toward equality in the workplace.
In my experience, I have been asked everything from if I have a stylist, to if I dress “nerdy” to better fit in my “role,” to what my reaction would be if approached to pose for Playboy.

If we want to see diversity in these fields, there has to be a conscious rejection of and intolerance toward remarks in the media that diminish these achievements.
One time when my music theory professor was a student in college, he had to accompany an extremely rude soprano for a recital. She treated him like dirt during rehearsals. Just before going on to perform, she made some really snide remark to him that ticked him off, so he transposed the piece up a half step. She cracked three times.

There is a special place in hell for people that are rude to their accompanists
