Probably not the soft tw@t...:frown:

Any turn of phrase that is suspected as being racist is subject to close scrutiny, especially in the USA; hence the euphemistic 'N-word'. Reports that a harmless word like picnic originated as the name of a lynching party only have to be voiced to be taken seriously and become part of folk-etymology.

In that context it has been alleged that 'nitty-gritty' is a derogatory reference to the English slave trade of the 18th century. The phrase is usually used with the prefix 'getting down to' and there is a sense that, whatever the nitty-gritty is, it is at the bottom of something. The suggestion is that it originated as a term for the unimportant debris left at the bottom of ships after the slaves had been removed and that the meaning was extended to include the slaves themselves. That report became widely known following newspaper reports of an 'equality and diversity' course for Bristol Council employees in 2005. Had the firm that was conducting the training known that their claims were to reach so wide a public they may have chosen their words more carefully.The general touchiness over language that might have had a racist origin is enhanced by the ongoing guilt felt by some communities that were formerly involved with the slave trade, for example the English sea-ports of Bristol and Liverpool. In July 2006, Liverpool Council debated the proposal that Penny Lane in Liverpool should be renamed to remove the association with the slave-trader James Penny. This was dismissed as ludicrous by many in the city, but the very fact that the suggestion was made indicates a degree of ongoing unease.
