Well it seems you’ve made up your mind. I can’t reason you out of a position you haven’t reasoned yourself into.
You seem to assume that a lot of people should or do have your intellect and education. They do not, and that is not their fault. You also make the mistake of simplifying what was an extraordinarily chaotic political landscape between 2016 and 2019. Finally, and most bizarrely, you seem to think it realistic to expect 90+% turnout in a general election which is, at best, astonishingly naïve.
But look, you do you. Obviously you didn’t come here to scrutinise your own firmly held beliefs. So have a good one.
