¿"Posh" Accent?

Please.  That is an atrocious--snobbish/snotty--way to describe anyone's habitual manner of speaking, whether one's own, or someone else's. How is it that no one in the United Kingdom seems to mind, or to appreciate, the fact that: "Posh," as a concept and as a standard of excellence, is odiously, sickeningly vulgar? ¿And, as it happens, intrinsically wrong?  Odiously, sickeningly vulgar, say, in the same way that it is to imply that "love" is anything other than an emotion without any physical implication (as it does, nauseatingly, in the American Hillbilly Dialect: e.g. "He's a-lovin' 'er"). And as it does not in, for example, Elizabeth Tudor's great, final Golden Speech.

Which, by the way, is not only astutely and irresistibly endearing, but a damned fine specimen of  Elizabethan prose--not unworthy of, say, Francis Bacon. Hint, hint.
