It seems to me that using the word "gender" in the way it has become lately is a big mistake. The standard English use of this word is in regards to grammar, when a noun can have a gender (male, female or neuter), and by changing the grammar of the sentence, the gender of a noun can be changed. But a person is not a noun.
Roe Vs. Wade is a great example of what happens when a body like the Supreme Court doesn't even know what a person is!!
Gender is germane to change, while sex, per se, is not.
In regards to a person's sɛҳuąƖ identity, it is not something that can be changed like using white out on paper and typing over the new edition. Whether someone is male or female is a matter of sex, not a question of gender.
While today there are bizarre tales of people having sex change operations (notice they don't dare say "gender change!"), the fact remains, that even after the surgery and hormone treatments, a male remains a male (however mutilated) and a female remains a female. Every cell of their bodies contains the same x and y chromosomes embedded in their DNA. Hormone treatment has no effect on DNA.
The first phase of this attack on language (and therefore an attack on popular thinking) was to stop using "sɛҳuąƖ intercourse" for the sex act, by shortening the term to "sex." So then a question about someone's sex suddenly implied a question about their moral behavior, as if to ask when they had "done" it.
Perhaps something could be put into law to make public misuse of the words "sex" or "gender" a misdemeanor or whatever, but whether that could effect a change in the way people think is another question. You can't legislate morality. Certainly under the Social Kingship of Jesus Christ, there would be some way of effecting a change for the better, but unless God metes out His Justice on our world, we're a long way off from having Our Lord recognized as King over our social world.
(There was a city in Pennsylvania recently consecrated publicly to Jesus Christ through the Immaculate Heart of Mary, which is good news, a step in the right direction.)
I think we can all do our part by not using "gender" out of place and to keep the words in their proper use as best we can.
