You seem to be confusing the now common "it's all about me attitude" in your response with respect and PC as though there wasn't enough confusion already. As an example of being PC one might make a statement to another such as, "I was just discussing last nights game with the little person down the street." That same statement when done with respect might be, "I was just discussing last nights game with the person down the street." An example of the same statement using the all about me attitude you describe might be "I was just discussing last nights game with that &*%$@#^ midget down the street.
Nonsense. Your last statement isn't the equivalent of the prior two. It's directed as an attack on the person rather than a neutral tone.
For examples of being PC, you can take the two following statements (trying to stay close to your examples):
Non-PC version: "I was just discussing last night's game with the midget down the street."
PC version: "I was just discussing last night's game with the little person down the street."
Most of them consider the term "midget" offensive. It's that choice of term, not the profanity, that would offend them. The PC version - which can be just as easily labeled the respectful version, would be to go by their choice of acronyms, which is "little person" or "dwarf".
You're specifically editing your language so that that group won't find it offensive.
Now consider this: "I was just discussing the game with Kyle. He's a little person, but he's one of the coolest f****rs you'll ever meet!".
F-bomb. Profanity. World is coming to an end. It's not the little people being offended in this case, and it's not an attack on his person. It's a compliment, but a different group might be offended at this: rather than the little people being offended it's the prudes of society.
Two sides of the same coin. Different people find different things offensive. Personally, profanity doesn't bother me, and a show that's funny I'll watch regardless. Witness "Office Space" - it's got quite a bit of profanity, lots of dirty jokes, and is probably the funniest movie I've ever seen.
