Not ours, I hope. There is a difference. Robert Hughes may be right to say in Culture of Complaint that 'the usual American response to inequality is to rename it, in the hope that it will then go away'. But the point about sharing a workplace with people is that they do not go away, and they are neither named nor 'renamed' in their absence. Of course all the inequality in the world does not vanish when we encourage respect.
Language is a collective product, and no one can control it or prevent it from changing.
PC language sets out to help us represent the social world the way it is now, not the way it was thirty years ago. In the process, it easily becomes coy, pedantic and prissy. But when it gets too absurd or fails to serve any useful purpose, people laugh, quarrel about it, criticise each other and come up with better ideas. Fussing a little bit about phrasing and names can actually help reduce the need for 'special delicacy' in talking together about important things. The price of retreating from this effort is one that almost all of us would have to pay.
