I hate this attitude that makes people watch their words. It may be true of public and influential personalities, but who cares your choice of words as long as you convey the message? I believe that everything and everyone can be laughed at.
Sure, you may feel offended inside. But you should at least understand that it makes no sense and refrain from sharing your "I'm offended" feelings. Same thing goes for the other end of the spectrum by the way: you can be sexist but as long as you don't act on it, I don't see a problem. That's what freedom is about.
