Nope. Blaming "political correctness" has always been a bad faith argument. Ever since Segregationists used it to rebrand their fight against Civil Rights.
Right Wingers trying to grift the Left, currently blame IdPol (Identity Politics) in the same manner. Which again, reveals their turn intention to undermine the coalition of Civil Rights and anti-poverty activists.
So it's always necessary to call out the intent of bad faith behind these rebranding attempts. We kept the receipts.
