At least if I know someone (imo) intelligent is in charge, even if they do (imo) bad things, I can tell myself that they do it for a reason, have thought about it and came to a different conclusion than me, which is "fine", I can deal with that. Maybe even discuss with them about it. On the other hand... Stupid doesn't think, has no reasoning behind its action and can't be reasoned with.
