It definitely doesn't sound right. I'm hoping/wishing that this quote was taken out of context. Can anybody with more insider context elaborate?

I'm very interested in the "internal cultural battle" over diversity issues at Github, because my school's CS dept. is having a lot of dialogue lately with similar rhetorical arguments. Teaching Assistants recently had a mandatory student-run training session that I perceived to be frighteningly one-sided.

Besides the photo, what else did the talk discuss?
