From England, this article by a man living in a formerly English neighborhood:

Well, no, actually. As the old saying goes, the definition of a racist is anybody who's winning an argument with a liberal...one who is, after all, used to setting all the guidelines for what passes for national debate, is insulated from the effects of his opinions, and doesn't much care for being challenged.[How my neighbourhood was lost to the multiculture, By Peter Whittle, Sunday Times, January 22]

In fact, this saying is only eleven years old, it's from Alien Nation, 1995. And here's the full quote, from page 10:

"Because the term "racist" is now so debased, I usually shrug such smears off by pointing to its new definition: anyone who is winning an argument with a liberal.Or, too often, a libertarian. And, on the immigration issue, even some confused conservatives."
