Ignorance can be cured, stupidity goes all the way to the bone.

Ignorant or stupid?

This is a sample of natural linguistic change. It's OK if it was done a couple hundred years ago but heaven forfend that it happen right before your eyes. No problem using the accusative/dative plural in the singular nominative in the second person as long as the ungrammatical usage was established as "correct" 400 hundred years ago but not today in the third person. It's OK to pronounce knight as though it were spelled nite but not nuclear as though it were spelled nucular.

I've said it before and I'll say it again: Y'all prescriptivists ain' got no respeck for the language. It's fine as long as it does what you want it to do, but you can't take it on its own terms.

Harrumph®!
