My goodness!
What a confused mess.
Obviously some people are trying to make what should be simple as complicated as possible.
Back in the 1950s, "sex" referred to biological reality.
"Gender" was a grammatical term:
"he" for men, "she" for women.
Then it was noted that society treated men and women differently, with expectations for each and roles for each.
And some people didn't like that.
And then it was off to the races, leading to the total confusion mentioned above.
Consider the lead sentence in Wikipedia's article:
"Gender dysphoria (GD) is the distress a person experiences due to a mismatch between
their gender identity—their personal sense of their own gender—
and their sex assigned at birth."
Back in the 1950s, the two opposing concepts
"gender identity" and
"sex assigned at birth"
did not even exist.
Sure everyone belonged to one or the other of the two sexes, but that was a property of the individual, not an assignment.
My, the intellectuals have been busy, creating what didn't need to be created.
One might ask who profits from this.
Well, here are two examples:
1. The various medical professionals receiving income for "gender care".
2. Various people in the "Gender Studies" departments in universities.
Goodness gracious, if it wasn't for this gender mess, they might have to find something else to do.
And taxpayers, health insurance payers, and those who support universities are paying for all this.
