Ya got the wrong link... Here is the correct one for NARTH:
http://www.narth.com/ Some of their members and speakers are associated with the Mankind Project. A couple of years ago, there was a bit of a hulaballoo when they used the MKP e-mailing list/notification system to promote one of their speakers. It seemed to imply that MKP endorsed them, given that only official communiqués were ordinarily sent out via that route.
The way I understand it, some MKP chapters, which were more "gay-friendly" than the Los Angeles one, raised a bit of a stink at the time. Whether MKP administration does, in fact, (tacitly) philosophically sympathize with NARTH or not is still unclear to me.
