If people get hurt by people using the term 'race' then they are too sensitive.
People may not like certain phrases, but what do you think you are doing by correcting people like that? I'm sure kingcool52 is fine with it, but what if you get someone use the term 'race' then you get hurt by it so you correct them and tell them to use 'ethnicity' which could just as easily end up hurting that person because they could consider you correcting them as being rude.
That's the problem with this whole mess, people that get hurt by certain phrasing think they are the victim and have a right to correct people yet don't think what they are doing has the same affect.
