HoneyBakedHam: Okay... I don't have any real issue with the point you are making here in regards to the idea that different racial, ethnic, or gender groups may have various strengths and weaknesses that are measurable... after all, elves are better in the forest than dwarves, but dwarves are better underground... (that's all based on science, right?)
But as a member of the community that stands on the left, quite a distance from center, I feel only a little compelled to make a few comments. etc.
The problem is, that the PC attitude is going way too far a lot of the times. Changing the names of things to "not offend" while the people who the name affects usually don't really care ... is that really needed? And this is the lightest form of existence.
Under PC, I also include those people who don't want to offend anyone so anytime you make a general statement they complain to say "not all of them are like that, how dare you say that" which is facepalm-worthy since general statements are called general for a reason (and yes, I'm against the notion that you should never use a general statement - thats how our brain works and we ALL generalize mentally).
It's maybe not true PC, but I consider it to be in the same spirit: reality versus some idealistic world where no-one is offended. Truth is, people are always going to be offended, and often by the truth. The bad result is, that politicians are often afraid of a PC backlash so work to hide certain facts.
A few years back, it was revealed that politicians had been hiding crime figures from the public for years because of what the numbers revealed (namely the high number of criminals among Moroccan youths which was over 80% for males in large cities). Because these numbers were hidden, the press and public were unable to put pressure on politicians to change this or to help reduce that number. Instead, the number steadily climbed for years until a change of government finally brought them to light. And this is what I consider PC gone wrong - even REALITY that might cause offense, is hidden.
In the end, I think PC does as much harm as it does good - it's the INTENTION of the person that counts anyway, not the particular words used. It's like this episode of Everybody Loves Raymond where one of the actors used the word "black" and they all gasp. "Oh no, she used the word "black"! PC has made that a bad evil racist word! It's African American these days! Sure in a few years, it will probably be changed again and be considered racist then as well, but lets gasp at the silly PC attitude where using a word to describe skin colour is EVVVILLL!". *facepalms*
