My particular problem was with the use of the word 'just' - it implies lesser, as if those who identify as CD, or even 'men in frocks' don't also suffer as a result?
But 'Cross Dressing' simply describes a behaviour - I think it's an erroneous assumption to believe that it is never linked to a degree of gender dysphoria?
IME, GD comes in different levels (and forms, which may or may not be mixed together). There is no simple binary, of CD or TS - there is a spectrum of feelings and behaviours?
