Good post and a worthy contribution. Used intellectually, and in specific circumstances, the "history" defence is valid, credible and necessary. Used glibly, as a catch all, it's just naked institutionalied racism. This is very clearly the latter. The contribution of the hound and codeword are insignificant, the word is nowadays utterly beyond the pale to any decent human being, the row completely detracts from one of the great feat of arms of warfare.
That's my ten penneth...I'm moving on, so should some of you.
