For the person that said:
“There is no scientific evidence whatsoever that gender biology shapes personality in any meaningful way.”
This is factually very wrong.
I’m quite familiarized with personality psychology and its biological correlates, the endocrine system and so…. As most thing human there is a gradation, but in general there is a clear bimodal distribution with a moderately big overlapping area.
There are extensive well established literature on the subject, but i leave you a few references:
Measured differences in personality according to gender following the Big Five model:
“By examining personality at the level of the 10 aspects of the Big Five, we demonstrated that gender differences in personality traits are even more pervasive than has typically been reported. In every one of the 10 traits assessed, significant gender differences were evident.”

A less dense reading that also includes informacion about the previous study: http://www.bbc.com/future/story/20161011-do-men-and-women-really-have-different-personalities
Cross cultural validity:
“gender differences are small relative to individual variation within genders; differences are replicated across cultures for both college-age and adult samples, and differences are broadly consistent with gender stereotypes. […] Contrary to predictions from the social role model, gender differences were most pronounced in European and American cultures in which traditional sex roles are minimized.”

Biology and personality — Genetics:
“The Genetics of Sex Differences in Brain and Behavior.
Historically, it was argued that such differences were largely, if not exclusively, due to gonadal hormone secretions. However, emerging research has shown that some differences are mediated by mechanisms other than the action of these hormone secretions and in particular by products of genes located on the X and Y chromosomes, which we refer to as direct genetic effects. This paper reviews the evidence for direct genetic effects in behavioral and brain sex differences.”

And a somewhat anecdotal study about testosterone differences between men and women, and the non-effect of socialization on them (The references at the end are more interesting that article itself):

This is far from pseudoscience.
