“Sex is genetic. Gender is a term for the manifestations of sexual identity, and therefore is subject to some manner of flexibility.”
Liberal doublespeak gobbledygook
If you have XX you can’t change to XY through behavioral, cultural, or psychological actions. Heck not even through surgery can you change XX to XY.
Words have definitions. That isn’t liberal or conservative, it just is.
The term “Sex” is the literal term for the physical differences in a species. That is the 1st definition of “sex”:
SEX - noun: “1- either the male or female division of a species, especially as differentiated with reference to the reproductive functions.”
As opposed to Gender, which refers to linguistics:
GENDER - noun: (in many languages) a set of classes that together include all nouns, membership in a particular class being shown by the form of the noun itself or by the form or choice of words that modify, replace, or otherwise refer to the noun, as, in English, the choice of he to replace the man, of she to replace the woman, of it to replace the table, of it or she to replace the ship. The number of genders in different languages varies from 2 to more than 20; often the classification correlates in part with sex or animateness. The most familiar sets of genders are of three classes (as masculine, feminine, and neuter in Latin and German) or of two (as common and neuter in Dutch, or masculine and feminine in French and Spanish).
And other definitions of Gender:
“the behavioral, cultural, or psychological traits typically associated with one sex “
And of course, it also has the definition “Sex”, as it is considered a synonym. But that wasn’t it’s primary use.
And since language is defined by its cultural use (sadly, but always the case), it is useful to know that the term “gender” has a different shade of meaning than “sex”.
I guess if you think it is important, you can argue to defend the literal definition of “gender”. That doesn’t seem to me to be where the real war lies, and not understanding how the language is used today makes it hard to converse with the generation we need to reach.
