I was at a conference a few years ago and I was having dinner with another professor and another person who was then student at a highly (Leiter) ranked department where I had also once studied. The topic of having children came up. I expressed some ambivalence about having a family and the graduate student replied that if I and my partner at the time did have a child, that child would be “a mongrel” (I am white and my partner was not). Would this graduate student have said this to a male professor? Perhaps he would have. I don’t know. But I think in general this sort of thing happens to women more than men.
