You know, every time I hear somebody complain about "political correctness" they follow it up by saying something really ugly and inaccurate. Then they complain, "gee, isn't it too bad that people don't let us use these dated terms anymore?". The reason we don't use the term "mulatto" is that there are a whole bunch of wrong assumptions rolled into that word. That there is any such thing as mixed vs pure race, for instance. The distinction is wrong. I mean, yeah it takes away your ability to describe the world a certain way, but it's because that way of describing the world is historically linked with murder, genocide, and slavery!
