Would it be possible to ban political correctness?
I mean, who decides what is politically correct and where the line is drawn anyway?
Are we to become robots, programmed to think a certain way? Is forcing yourself into a mold you don't fit into really for the "greater good"?

No we can't "ban" it. What's commonly called PC is the more extreme fringe of the social construct we all live under. The same one that tells us not to walk out on the street naked or act like a dick.
And if we were to try to "ban" it we'd have an impossible time trying to "define" it.
Agreed!
Censorship is notoriously difficult to administer. And ultimately ineffectual since people just find a way around it.
Language is a living thing. It evolves to meet the needs of society at any point in time. 25 years ago only computer geeks were aware of the term "internet" and what it meant. Today everyone uses it as part of the language.
Political correctness is just a means to avoid giving unnecessary offense. At least that is the stated objective per the definition. It has been turned into a partisan blunt object to beat others with.
What baffles me is that the language is so rich and can be used is so many effective ways that it seems pointless to not exploit it to the fullest rather to remain fixated on a tiny subset of objectionable terms.
But if your vocabulary is limited then that is a reflection of your intellect IMO. Suffice to say that those who shun political correctness are themselves, in turn, more than worthy of being shunned for the paucity of the content of their communications.
