This is always good for a flame war on alt.transgender. Some people use the acronyms MTF and FTM respectively. I'm trying to make these definitions simple, but sometimes I have to over-simplify. Still More Words I recently picked up the book Blending Genders , edited by Richard Ekins and David King. First up, it only caters to the M2F TGs.
Some people think that all TGs are queer, and others think that all queers are transgendered.
