For those of you that think that biologically there is only XX and XY, look up XXX and XXY, for example. Or that other developmental things can go amiss look up freemartins in cattle. I see no point in making snarky remarks about transgender folks. They have enough physiological problems to deal with as it is. Why would you want to push them over the edge mentally by such remarks on the forum or the internet? Seems flat out mean to me.
