I was fairly deep in the alternative/left/punk/feminist/anti-Apartheid community at Penn State, and I knew of only one out transwoman. IIRC, she generally steered of the campus feminist scene (which was my main scene). It may have been because she felt would not be embraced there. I myself was confused and deeply closeted, and tried rationalize my feelings by saying to myself and others, "Well, I don't feel like a man because I'm conscious of patriarchy and hate it."
