This type of hyped up placeholder is _exactly_ an example of political correctness gone too far. It's exaggeration. My argument is not even against purposefully using words that are offense. It's about how there are so many words that are deemed offensive today that I can't even keep track of what they are.
For example, calling one of my own non-homosexual friends a "faggot" or "gay" is offensive. Even though I'm not homophobic and personally find it to be a funny, playful insult.
I may or may not be factually correct about this, but in general (I use the word general here in the sense of more than 50%) of those offended seem to be minority groups. I.e. homosexual, African Americans (this is easily to confirm by census results in a country), Semitic groups, etc.
The issue seems to be whether we should give up the ideal of not offending people as there exists no such fundamental right not to be offended.
