I think, perhaps, it's because there is some "crying wolf" going on in PC culture today, with things that really aren't intended as racist. So when it comes to more serious things like this which may actually be racist or prejudiced, unfortunately, some people lose sensitivity and assume you're being overly dramatic. I think that may have a lot to do with some of the backlash that occurs. In an effort to be totally PC in everything, we have lost some meaningful perspective about what it means.

To me, Politically Correct has always been about displaying mutual respect and tolerance, but it in my opinion it has been taken to the point where we're encouraging people to become offended and outraged over way too much. As a society, we also need to be able to deal with tolerating differing opinions.
