There is an explanation using some old stereotypes, to connect with others:
Men share their knowledge and ideas.
Women share their emotions and feelings.
Men share their knowledge and ideas.
Women share their emotions and feelings.
Isn't that tautological though? Why would a simplified characterization applicable to the mass of normies contain guidance equally suitable for the small percentage of divergent edge cases?
Looks like quite the stereotype you've identified "nonbinary people". You'd do well to start comparing yourself to actual people instead of the stereotypes you have of them.
They are right that if you do not match either of the stereotyped genders then you can’t learn from gender stereotypes.
Sure, it’s better to learn from people in a holistic non stereotyped sense but that is not what was being suggested.
