We learn our instinctive, natural language usage in early childhood, that determines how we naturally speak in informal environments. I almost never use "whom" and usually use "me and X" subjects even though I know that is "wrong" in the formal language, you can drill grammar into people's heads as much as you want, it will simply not change people's natural speaking habits.
