Perhaps the ones that you like to deride as thickos are just happy to derail whatever plans superior beings like you would like to implement? I mean, it's not easy to be superior and liked, is it? Tough call for anybody to try and take that on - telling people they're thick and hoping they'll march to your tune. Kudos for anyone brave enough to have a go (although the Greek language could probably provide a more appropriae word than 'kudos', eh?)
I don't know about "thick" but I would suggest that anyone (who isn't a wealthy business owner / millionaire or the like) that votes for this government after the last few years, is either blindly stubborn, easily lead, or a bit too daft to know who is and isn't acting in their best interests. I don't think one has to be thick to fall into those categories but it is a desirable quality for the role
