Against a total maniac I'd agree with that, but anyone who can play the style relatively well is going to run you over when you have nothing, make you hate your marginal hands, and not pay you off when you have a monster. If you let him run you over by folding average hands then you are playing right into his stlye. I'd get in there and gamble with all but extremely ragged hands trying to catch some pair to try and get paid. Even here K6o is borderline, and if I knew I could get tons of action on my bigger hands I'd dump it, but I think the preflop decision here is pretty close, so I wouldn't worry about it. If you wait around to flop trips or other big hands before getting aggressive against a maniac then he is going to eat you alive.
