Rereading it on ArM5 p.59 or in the OP, I don't see at all, that it claims or is meant to be "the way to play gender non-conform." It is about habitually dressing and acting as the opposite gender. It does not give or imply any motivation for it, but immediately cuts to the chase of typical consequences "in Christian and Muslim lands" - which it exaggerates.
This exaggeration and the Flaw's insensitive naming IMO need to be changed.
