Contrariwise, some transsexuals feel that their transgender status is transitory. Some feel that the binary gender dichotomy is correct -- it's just that they started on the wrong side of the line. Once they (members of the subset) have "finished" their transitions (with or without hormones and/or surgery) they feel they have made it from the wrong gender to the right one.
Eventually, some stealth transsexuals get comfortable enough to decloak and mentor transsexual newbies or advocate/rabble-rouse for their cause publicly.
