What kind of proof would I have to provide for the claim I made? (i.e. that from my experience people are generally not too sensitive, but instead the people crying about political correctness say outrageous and horrible things that I don't think they should say)
That's my point. Because the topic is subjective and because your claim is based on your subjective view of the matter, you cannot provide any more proof than I can provide. I take the exact opposite side of this matter but I can't make a better argument than yours.
