Well I think most people on both sides of this debate (and in general) are pretty stupid and easily swayed by propaganda (it wouldn't really be a thing if it didn't work would it?) which seems to be the general purpose of most of the mainstream media. And most politicians are always going to lie and spin and ultimately don't really care about what the people want, only what they want. Which is why I remain unconvinced hard Brexit is even a possibility. We only have a few months to work it out? If they can't it'll get extended. Neither the government nor the EU want a hard Brexit.
We never get anything resembling the truth from the government and frankly, even if and when the truth does come out, and it's horrifying, nothing happens because their lapdogs in the media spin it - Just look at the Iraq War situation. Everybody now knows that war was bullsh*t founded on lies that the people telling them knew to be lies, but eh, so what, it's only over a hundred thousand people dead and an entire region destabilised for decades. You think these same people give a damn if anyone wants the Brexit process to be transparent or accountable? They're above the law. They're not supposed to be and they'll sing platitudes about the "rule of law" and how important and great it is, but when it comes down to it they are. They'll do whatever they want - The politician's main concern in this process is not seeing through the "will of the people", it's being seen to do things that are vote-winners come the next election. That's the state of politics, that's the state of "democracy".
The Brexit process is being followed through for the survival of the Conservative and Labour parties not because they want it, but because if they go back on it they stand to lose voters in massive numbers. And that might be terrible but I'm not sure what the alternative is, because when you have a ready-made voting bloc of however many million people voted for Brexit - Labour, Tory and otherwise, that's a hell of a base for someone (be it Farage or whoever) to galvanise against a parliament who betrayed them by undermining democracy. Not necessarily my belief, but you can bet it would be their words. And they'd find receptive ears.
