First, even if we give you the benefit of the doubt and say it is factual, you do not need to lie in order to spread hatred, or at the very least provoke/troll people. "But it's true" is a childish defense in that context. If you were being honest, you would defend the practice of provoking/trolling people regarding gender identity (rather than merely defending the generic concept of saying something factually true, which is akin to the classic "I'm not touching you" game of provocation). And to be clear: I am not arguing against that theoretical argument in this comment - I am just saying that you should make that argument, since clearly you believe it but are being oblique about it.
Secondarily (and I do mean secondarily - it's entirely subservient to the first point and basically just an exercise in argument): The statement isn't factual, since it's just disagreeing with a context in which a word is used. It's literally a semantic argument, which is always more or less subjective.
