The point is to force people to say 2+2=5 and them to treat them like women even though know better. It's a form of mental domination. It reminds me of this quote from Theodore Dalrymple:
“In my study of communist societies, I came to the conclusion that the purpose of communist propaganda was not to persuade or convince, not to inform, but to humiliate; and therefore, the less it corresponded to reality the better. When people are forced to remain silent when they are being told the most obvious lies, or even worse when they are forced to repeat the lies themselves, they lose once and for all their sense of probity. To assent to obvious lies is in some small way to become evil oneself. One's standing to resist anything is thus eroded, and even destroyed. A society of emasculated liars is easy to control. I think if you examine political correctness, it has the same effect and is intended to.”

You're absolutely right. Orwell also put it well.
and even more relevant to the 2+2=5 point,
