Hmm... yes I think that many are still wrestling with a perceived stigma or just want to show that they are closer to one end or another of the spectrum, or that they are only a little away from 'normal'. It works on the other direction too, I've read remarks by TS's elsewhere that were disparaging of CD'ers for being in between.
I wonder though, where one must be on the scale to be no longer transgendered? Most of the women I know have some 'male' traits, same with the men being at least a little 'female'. I think that less than 1% of either gender that I've met could be considered 100% one or the other, depending on what traits you ascribe to what genders.
Could it be that we are all transgender? Every human being?
