I think I quite clearly have demonstrated I know what the OP is getting at if you read my posts. I dont recall saying that anyone has a right to go through life without being offended. What I said in summary was that if you decide you want to offend someone then prepared to suffer the consequences.
So, you have failed to grasp the issue.
The issue is NOT about having to take flack for saying something that may or may not offend someone, but the fact that people (mostly the left) will use this not because they are offended, but because they want to put fear into their opponent.
'I better not say that, or I'll get called a racist"
Or...
You get called a racist without merit, but now have to spend time proving you are not a racist, all the while, knowing that if they said it, then others will believe it, no matter the amount of proof provided.
A prime example. George Zimmerman. He tutored black children and not once has he ever exhibited a racist tendency. The media used race by careful editing of the 911 call to make it look as if he was racist.
This is the use of PC (meaning words that a political ideology fine offensive) in this case was artful and for the purpose of intentional harm to reputation. Not out of some misguided notion of keeping conversation civil.
