Isn't being PC just a way of not being rude and trying to be fair?

Okay, so every once in a while I see people comment that they hate the left because they are always so PC and they want to be able to tell it as it is. My question, is how many people would really like that kind of honesty themselves?
Second question.
* If you do think being PC has gone over board, would you really want everyone to blurb out every thing they thought of you?*
