I just wanted to add something here in addition to my earlier comment ... To me, with my background, the statement "Everyone doesn't X" means the following: Everyone doesn't X. It is the case that everyone does not X. It is the case that every person does not X. It is the case that for every person, they do not X. Choose a person: they do not X. No person does X. If I want to negate the statement "Everyone does X", perhaps keeping as much of the original phrasing as possible for effect, then I would say: No, not everyone does X. Natural language is what it is, and I accept that to some people the appropriate negation is, in their idiom, expressed as "Everyone doesn't X." I'm just saying that my idiom should be accepted, just as yours should, and if you use that form, you will fail to communicate effectively with me. I'm not claiming I'm right, or you're right, or anyone is right. Linguistics research accepts that we should allow each person their idioms. I'm saying that for effective communication, the differences should be understood and allowed for. And I won't say any more on this topic. At least, for a while.
