Firstly, no, that position isn't 'scientific'. The scientific portion of the equation comes from the separation of gender and sex along with the psychological and sociological expectations of how someone conforms to a given gender role. I see this often that people take a disingenuous stance and then claim it's 'scientific' when its anything but.
Secondly, that argument has a lot of baggage associated with it. Transgender people get banned from the military because they 'cannot change their sex' or 'transgender people lose their jobs because they don't conform'. It's an argument around taking away the rights of a certain group of people and it shouldn't be surprising that people don't want to associate with that.
