On a side note, as a non native English speaker, the double negative always sounds really awful to me :) You can call it dialect all you want, it just doesn't make any sense.

It's amazing how difficult it is for people to get past the trap of thinking that what's familiar is "correct."
Two negations on different parts of the sentence also don't reinforce each other: "not everyone is not doing it" if equivalent to "some people are doing it".
To me treating double negative as reinforcement of the negation is a weird, unintuitive corner case that doesn't fit in the broader framework of the English language.
But be aware that these kinds of arguments bear striking similarities to the arguments we have about the singular "they", which someone on a message board will always seem to have ironclad logical arguments against, only to find their argument foiled by incontrovertible evidence of its acceptability in Standard English.
