If you have an hour available, I highly recommend the full video
At 19 minutes into the speech, she mentions "I fled from feminists. I just wanted to be seen as a scientist."
This reminded me of a conversation in a mixed group of interns. As I recall, it was shortly after the death of Jessica Dubroff, and one of the male students had made a comment about female pilots.
And yet, at that time I didn't feel any particular connection to feminism. I just wanted to be an engineer.
Most of my experiences to that point were along the lines of "A woman needs a man like a fish needs a bicycle," or some of the more outrageous statements about men coming from NOW. As a straight woman, and as mother to a boy, I do find value in the males of our species. I don't feel the need to put anyone down in order to raise my own value.
But in the years since that conversation, I have traveled a journey similar to what Professor Hopkins describes, uncovering intrinsic bias throughout American society. And so, like Professor Hopkins, I now consider myself a feminist.
