The US State Department has a "Chief Diversity Officer" (doesn't every agency, these days?), and he says that a number of common phrases are racially or culturally insensitive or insulting: "Hold down the fort", he claims, is potentially insulting to Indians. Really? Who died and made him a Chief? Wouldn't that title be potentially insulting to Indians?
And "rule of thumb," he wrote, can according to women's activists refer "to an antiquated law, whereby the width of a husband's thumb was the legal size of a switch or rod allowed to beat his wife."
Dude, ever taken a close look at the Moo-slims? Get real, and quit making stuff up.
