Becky,
I understand your sentiment but it is not really fair to admonish the OP for not becoming one of the trans "shock troops". While some people make the decision to come out to the world irrespective of where they fall on the TG spectrum others for reasons we cannot fathom choose not to. Also I am not sure what you mean by those who stand up are usually gay? Are you talking about gay cross dressers or the LGBT community writ large. While there certainly plenty of gay CDers out there telling the world about being TG, I am also quite certain, if this site is any indication, there are plenty of straight CDers out there who educate the Vanilla World as well.
