In most political debates, including Scottish independence, i think that it is poor form, unnecessary and untrue for one side to call the other thick.
Brexit is quite unusual in this regard as i haven't yet seen a good argument for it. By good, i don't mean persuasive, i just mean vaguely coherent and even slightly plausible. The sort of gibberish that could only be believed by utter morons passes for an argument with these twats.
