Your point being?
the prescriptives for English were very different in the 19th century to what was recorded in the 20th
You still are missing the distinction between grammar and style. On a good day, my own style is more Augustan than anything else. Regardless, the rules of grammar prevailing today were standard 150 years ago and largely so a century before as well. "Between you and I" will always be a barbarism not because it violates a prescriptive canon or because it isn't used by the right sort of people, but because it's illogical, contradictory, and confused -- defects that cannot evolve away.
My point being that “proper” grammar has never been the language of the masses and anybody thinking there’s a sudden change now just hasn’t been paying attention.
I’m not missing anything, you’re changing what I said in a desperate search for something to be right about. The rules of grammar change.
Barbarism?! BWHAHAHAHAHAHA. See that’s exactly the egotistical BS I was talking about. Grammar nazis are just stroking themselves. Really, get over yourself. You’re not that cool.
