Discussion on answer by Emily: "Transgender" versus the obsolete term "transgendered"

ive never seen a more needlessly politicized or passive-aggressively domineering post on stackexchange

Re: "Transgender is not a verb that makes sense, so transgendered is nonsensical": I think this is a bit glib. The suffix "-ed" often means "having", as in "brown-haired" and "blue-eyed" and "female-bodied"; so "transgendered" makes decent sense as "having the opposite gender [from one's biological sex]". The community has rejected the term, and we obviously need to respect that, but we can still acknowledge that, as with many linguistic choices, there was a significant element of arbitrariness or at least path-dependence.
