We are natural beings, we observe, categorize and mold our language through it.
Our brains are so accurate in pattern finding you can see someone you know at night 100m away and you recognize them.
Our cognitive apparatus can detect the proportions of male and female with ease.
Now comes the trickery! rubs hands
To condition a person to see X and to force him to say it is Y or else he faces punishment is a tactic of demoralization.
If you beat someone so bad that you rub their face in blue and they are coerced to say it is red, you have victory over their cognition.
That means now you can invent anything and coerce people into not seeing it, or, even worse, seeing the exact opposite.
Cognitive dissonance can only be perpetuated in a cognitive demoralized target.
And if they demoralize our cognition, they demoralize our only tool to perceive, adapt and react.
I think that what makes it worse is that they don't even try to be internally consistent. Leftists will say that men can get pregnant. Then when discussing abortion, they'll say that only women can opine because men don't have uteruses.
