I actually think that Caitlyn doesn't actually help regular CD's as much as people think. Let's be honest, a large majority of us here have no real desire to transition. a few of us will, and good luck to them all on their journey, but Caitlyn does far more for transgender issues than she does for CDs.
People like Grayson Perry and Kiefer Sutherland do more to help people understand that some of us just like to wear a dress from time to time (or every night in some cases). But let's be honest, the two questions most prominent when we reveal to friends or family are 1. Are you gay?, 2. Do you want to be (or do you feel like you are) a woman?
I would rather see "regular" crossdressers having more media time and showing the world that some guys are exactly like others except that they prefer to wear something cute and slinky rather than some drab jeans.
Regardless of all that, I'm proud of Caitlyn for her courage and strength and our struggles for acceptance don't in any way diminish the work she has done for the community as a whole.
