Very often Stewart Lee is a prize twat, and I'd rather eat my own liver than watch his TV show, but christ he was bang on the money with that quote. Yes, PC does go mad sometimes, but only at its extremes. The likes of the Daily Mail would have you believe that [i]everything[/i] about PC is wrong and evil and designed to turn the so-called white middle classes into oppressed minorities. Utter bollocks. At heart, it is a good thing... it's just that some people don't know when to stop.
I'm old enough to remember when the Race Relations Act was first discussed and then introduced in the mid 70s. Incredibly, it was coloquially referred to at the time as the 'N*ggers W*gs and C**ns act' -- such were national attitudes then, even within certain sections of the media. Imagine if absolutely no forms of PC existed, no anti-prejudice legislation or race relations legislation, nothing. Imagine that? the BNP can.
