<Snipped quote by Dynamics>

Probably because I'm using definitions? Saying that human asexuality and biological asexuality are the same or that one doesn't exist at all, classification as a sexuality aside, IS wrong. As is saying that sex and gender are the same thing. :/ 
Where is the issue here exactly?

I think it's that in Christianity, biological sex and gender role are identical and inseparable, but the idea that sex and gender are separate sends the message that to be a different gender from your sex is okay.
EDIT: By gender role, just to clarify, I don't actually mean "you're this gender so you have to do this"; I mean "this is what you are, although it doesn't necessarily have any connotations as to how you're supposed to act." After all, under my convictions I'm fine with a male who holds traditionally feminine traits and mannerisms, or a female who holds traditionally masculine traits and mannerisms.
