When I see TRAs refer to a Gay man or Lesbian as "cis", especially the kind of TRAs who want to shove the term right down your throat, I see ignorant fools. What makes them fools is assuming that the way they experience gender is the same way everybody else does or should. What makes them ignorant is their lack of knowledge about how Gay people relate to gender; many of us have our own difficulties. Just because you aren't trans, that doesn't mean you are or have always been comfortable with your sex! It's another example of why one group should never dare presume to define another group.
