If anything is a social construct then everything is a social construct.
Gender, we are scolded, is a social construct and we are not very graciously informed that the common understanding of the word gender is wrong. This is followed by the lecture on the true definition of gender which just so happens to mean whatever you want it to mean EXCEPT boy/girl.
How do these people fail to realize - what does it matter? Gender is a social construct, right?
Ah, the folly of susceptible youth and their groomers.
