As we have seen asking the general public about an important topic leads to a situation like Brexit. Just because ppl have an opinion about what the priorities should be does not mean they have the slightest understanding about what the is happening in the world. The MPs are the ppl claiming to know best so you should trust them that they are doing everything in your interest and if they are not then it is your right to remove them from power. Having the average Joe decide on external politics is one of the stupidest thing you can do (e.g. Boris Johnson).

I do find your argument for Brexit to be a bit better than the average but employing the same logic London should just be a separate city state because there are ppl outside who vote against London’s values (openness and inclusion). I’d be the first to admit that in that vote if asked I would vote for an independent London from the U.K. and this is exactly why general population should not be making these descions.
