WHAT HAS HAPPENED TO OUR ENGLISH LANGUAGE? PART TWO

I forgot to add one other blatant change in the English language and how did I find it? Was typing a story and writing "The man who..." when a red line appeared under who. What, I thought to myself and so I changed "who" to "that" and Word accepted it. Made absolutely no sense to me at all.

When did who become that? A person isn't a "that."

I thought back to a couple of old movies whose titles are: "The Man Who Shot Liberty Valance" and "The Man Who Came to Dinner." The movie titles were correct in the usage of grammar. But try typing in either title on your computer --better if you have Word and see if you don't get a big red line under "Who."

I'm sure that this change has happened for people are never sure whether to use who or whom. But to change either word to that is ridiculous!
