Well, I'm glad you made this comment, poorly phrased as it is. I went back and double-checked the scientific definitions of the words I used, and I included a word as a synonym where it actually is not a synonym. I've gone back and fixed my comment to avoid spreading misinformation.

Now to answer your accusation and your question, in that order:

First, the accusation that this is "my position" and a "claim"-- that is not the case. This is the established consensus of the scientific and medical communities, and I am just repeating what they said. If you have a problem with that, go to your local hospital and argue with a doctor or something.

Now, for your question-- I didn't say anything resembling that at all. I corrected their terminology from "biological sexuality" to just "sex" because that's literally what biologists call it--sex. Then I made the points that sex is based on lots of traits, not just the one, and that there is a lot of variance in what we call "male" and "female". That doesn't deny the existence of sex, all it does is say that biology mostly operates in spectrums, not binary systems.
