The left sure loves to make sure everyone knows they love science until it comes to the male and female sexes. Gender is a social construct. A sex change does not change your sex. It merely changes the way you look, even as trash mags post stories like, "Man has baby". That isn't possible and it isn't science. Sex/XX and XY is science. Anything outside of that tiny fractional norm, in science, is considered a syndrome. 

If anything it's conservatives supporting science, while the science deniers on the left claim that things like gender fluid exist. You can attack them, their religion, but it's just a red herring. If you respond to this with anything other than ad hominems I'll be surprised. If you ignore the science of it, that will speak volumes in terms of your denying science, unless it suits your agenda.
