I'm not sure whether RGIII is referring to the renewed effort to change his employer's team name, or the recent coming out of Jason Collins. But either way, I'd like to know what "tyranny" is preventing RGIII from expressing himself.
To wingers, "political correctness" just means "not being able to express offensive or bigoted ideas without being publicly rebuked for it." They want the "freedom" to say whatever they want, but they don't want to extend that "freedom" to anyone else to say whatever they want back.
Again, self-awareness and logic aren't their strong suits.
