I definitely think people are afraid to be called out for being politically incorrect, and I think that's wrong. Unfortunately, too often the words sexist, intolerant, xenophobic, homophobic, Islamophobic, racist, bigoted, ect. are thrown around and misapplied, which makes it hard to make actual arguments sometimes without being labeled one of the above. For instance, if someone were to make an argument against Affirmative Action, they would most likely fear being called a racist, with good reason, and would have to spend a significant amount of time explaining why they are not racist rather than why they are opposed to Affirmative Action. Chances are, their views have nothing to do with race, but they may not get to explain themselves before someone gets mad. Those speaking out against gay marriage or abortion are often faced with similar dilemmas. Whether or not you are for or against any of these is irrelevant; I think it's fairly undeniable that many of us, especially those on the right, spend a lot of time walking on eggshells.
