It's not my intention to not work with women. I do collaborate with women. I am just saying if I am being put in a position of power in teaching, and I can choose between male and female undergrads, I would rather not be in a position of power over females in this current climate because we are at a hyper-sensitive stage.

There is no specific gain for them being taught by me instead of a female PhD student, and there is only risk for me, so all things being equal, I am suggesting that this is a stance many men might being to take or at least find themselves wondering about.
