This came over the TransMuslims list - a member asked a friend of his about this issue, and she responded as follows. I have no further information.
Unfortunately, the petition is not very well written, and Zucker may chair the whole committee on Sex, Gender and Paraphillia, he doesn't have direct control over anything trans related. That is in the Gender Identity subcommittee, headed by Dr Cohen-Kettenis who actually has a good head on her shoulders.The sender notes, "Anyone notice a distinct lack of transmen?"
If you want to complain (and I STRONGLY recommend you do) here are the contacts you should be sending it to.

Zucker is pure insanity. His policy for dealing with pre-puberty transkids is to first deny them all "cross gender stimulus" (toys, TV, even drawing that corresponds to the opposite sex), then when that doesnt work to prevent them from even playing with, or contacting friends of the opposite sex. He has said "transition is an unfortunate and totally avoidable outcome in gay youth". He advises parents and school administrators NOT to provide information to fellow students so that a transyouth may be "peer pressured" (read: bullied, physically and verbally assaulted) into a gender normative role.
Blanchard is also in there, though he is heading up the paraphilia sub-comity. Blanchard his half of the half-brained idea of autogynaphillia (the other half is Bailey). Their theory is that there are only three types of transpeople
1) men who are too ashamed of being gay so they want to be women so they can be straight men
2) men who want to masturbate with a vagina.
