Once again the title of the article says ‘gender’ but the entire article only mentions sexes. Come on…

A brief explanation:
‘Man’ and ‘woman’ are now binary references to the individual’s gender if known to be such, or appearance if said individual presents as mostly masculine or feminine in a social setting, as the terms have always been used to refer to a person. In contrast, ‘male’ and ‘female’ are references to the individual’s sex and genitalia. Gender is not sex.

Additionally:
Gender is the name given to an aspect of personality relating to a few traits that have been defined by current societal ideals as masculine or feminine, quantified with a whole set of labels because people must be quantifiable by tickboxes, apparently. Sex is originally assigned at birth by many hospitals and population censuses once the existence of reproductive organs on the individual has been verified as male or female, and regardless of whether an internal reproductive system transplant takes place, can be changed.

Older folk are confused, because they’ve been referring to sexes as genders for decades. We need to get this right.
