I hear you bro, I just thought that a double negative sounded proper in this situation, normally I'm a "Grammar national socialist".
The term "Grammar national socialist" is quite improper, as I've yet to toss somebody into a oven.
The double negative wasn't like, "Oh god, forget, double negative, I am going to take my English textbook and beat them to death."
Still, I'm a little bit annoyed by double negatives.
