The leftist premise is that people are empowered to dictate what other people think of them. It started with enforcing the delusion of a homosexual identity. That succeeded so they moved on to gender identity. The whole concept is delusional.
Facts: There is no such thing as “a homosexual”, gender is physical reality, and nobody gets to say what others must think of him.
Additionally, from the Oxford dictionary about the history of the word gender used to refer to sex...
Originally extended from the grammatical use, sometimes humorously, as also in Anglo-Norman and Old French [since the 15th century].
In the 20th century [since 1945] as sex came increasingly to mean sexual intercourse, gender began to replace it, in early use euphemistically, as the usual word for the biological grouping of males and females.
It is now often merged with or colored by [gender identity] “The state of being male or female as expressed by social or cultural distinctions and differences, rather than biological ones”.
Sure they do!
That's freedom of speech!
But...
...nobody has to go along with what brain damaged folks tell them they must.
