Since I am coming to grips to the fact that I have dual identities, one that I help to tap in to by crossdressing, I consider myself gender fluid and thereby transgendered.
I consider those who are transsexuals also transgendered, since they still do not associate to the sex which they are born with.
The only people on this board that I would not consider transgendered are this who simply dress for either sexual sastifaction, or those that simply like the feel of women's clothing, as they still consider themselves male in this regard. "Drag Queens" for the lack of a better term , do not fall under the transgender umbrella either, since their drew MAY only be for entertainment purposes only, and not to associate to being female or partly female - but I can not speak on their behalf.
This being said, this is only MY opinion, and that from a psychological and/or social standpoint, I may be totally off base.
