How did all this start? Has some sort of Political Correctness always been there throughout history? Is it dangerous to be politically incorrect? Are the thought police gaining in power? How does it impact free speech? Do you feel like you can say anything without consequence? What about challenging the power structure, how safe is that now days? Is it good that everybody agree on most things? Does it unify the state, or does it make the little people more manageable. Ask yourself how easily do I accept ideas like global warming, peace on earth, equality, social justice, capitalism, socialism, botulism, libertarianism, strong defense, terrorist threat, forcing vegetables on children, and banning oversize sodas.
Focus Test: If you read the above paragraph and the word "botulism" stuck out as out of place your have a high degree of critical thinking skills and are probably not susceptible to political correctness. If you missed it you are probably tired and need a cup of coffee.
