I suppose most people don’t understand the difference between being neutral/objective and being politically correct. A neutral and objective observer can still be critical about what he observes. A politically correct observer cannot voice any criticism.
I suppose you could say that being neutral/objective is being at the origin, while being politically correct is being exactly halfway the two extremes. When one extreme is larger than the other, the two are not the same.
My aim is to be as neutral and objective as possible. I have no desire whatsoever to be politically correct though. I voice whatever criticism I see fit.
