The phrase “check your privilege” is nothing more than an attempt by an opponent to shut down debate via argumentum ad hominem. And it’s complete bullshit.
The rules of logic and debate dictate that one is to attack an opponent’s argument, not the actual oppnent—which is exactly what “check your privilege” does.
Keep in mind that I am, in noway, saying that privileges don’t exist. They clearly do. What I’m saying is, as dictated by logic, that “check your privilege” is not the proper modus for argumentation.
