Good question, with sexism and mysogyny being my quick answers. This is one of the special gifts of being transgender for me. To have lived "as a man" when I was often expected to "take charge" and now being incapable of even driving a car is really too funny. My friends were quick with the sexist jokes when I first came out but that reveals more of their binary thinking than our truth. One of the guys suggested that i should go hang in the kitchen with the other hens. Cluck cluck.

I am a community activist and am part of meetings where men now try to talk over me or dismiss me as emotional. This is one reason I have not altered my voice much and can still whip out a resonantly vocal claim to the floor.
Playing the great grandma card can be fun too. It can be kind of a reverse bully pulpit and amusing to employ.
I say enjoy the perspectives that few will ever know so deeply as we who have lived it.
