“I'm just telling you why I believe what I do.” This isn’t a matter of belief! It’s not my opinion that “scare quotes” is the original phrase. Your suggestion that “scare quotes” is wrong, or that somebody misheard it, is just factually incorrect. I’m not talking about the other ways people mangle the English language. We could talk all day about various mistakes people make with English and it wouldn’t change the facts of this example. So maybe it *should* occur to you to research information you present as fact. Especially if you’re “correcting” somebody. Any single person’s experience, yes, even yours, is a terribly poor guide for the correct use of language. That goes without saying, no?
