I didn't say that. The "if it exists" I wrote came from "women may be biologically" from the parent. I'm disputing the statement that it's biological. The burden of proof is on whoever is making that claim.
why else would you write "if it exists" if you already knew a difference existed? you would just say that you dont believe its biological in that case, so it seems like youre trying to go backwards and deny your own words here
