This discussion is full of stupids who reject rationality and I don't care to continue it. Let's talk something else. Now if any mon should be Dark Type, it should be this guy. No not just cuz it has some black on it, tho that helps. And I understand Poison already does a fine job of conveying it's villainous qualities. But it should be Dark because of the whole scary hood face schtick.
Arbok's major design gimmick is it uses a false, threatening face to scare opponents into paralyzed fear, and that's a VERY Dark Type thing to do. It uses fear as a weapon. It intimidates prey in a very underhanded way
