People who think political correctness infringes on their freedom of speech don't understand property rights. You have the right to say what you please, but not the right to say it where you please, because you don't even have the right to be where you please. If you want to rant about representational minorities all day, please feel free to go do it at a public park. Just because you're free to be rude doesn't mean privately owned businesses are under any obligation to provide a platform for that freedom. In this sense, it seems it's the left's turn to complain about trespassers.
