I’d like to think that we are smart enough here to make our political points without resorting to racial epithets that some may find offensive. Your intentions are no doubt in the right place, but such language cheapens our position the same way it was wrong for Rush Libaugh to call Sandra Flouke a “slut,” even if she happens to be one.
With all due respect, "slut" is not one of those proscribed four-letter words. It's part of the King's English, describing a female who is overly-promiscuous.
As such, "slut" would appear to be an apt description and, thus, a legitimate use of the word.
