The problem with words coming from some, uhm, ideological framework, is that by using them you kinda implicitly accept the framework. Which some people refuse to. To imagine how it feels like, try using words from a framework you strongly disagree with -- even if you construct a sentence you technically agree with, it just feels wrong.

Sometimes the words become a part of common vocabulary so much that people talk about e.g. "third-world countries" without necessarily accepting Mao Zedong's Three Worlds Theory (or even being aware that such thing exists). Words like "privilege", however, still have their origin obvious.
