The reasons why Water contains so much s*** and Ghost contains the least s*** is because they're the most populous and least populous types. So really, saying Ghost has your least amount of hated pokémon isn't that impressive, but is still something.
Also Sableye is awesome for the fact it has no natural weaknesses alone (let alone the fact it has an awesome design), so I dunno what the hell you're on Shoenin.
Of course, thinking of no natural weaknesses got me thinking of Spiritomb. Aaaand now I have to cross both Ghost and Dark off my list. F*** you Spiritomb!
