I think we can safely say that since the ref was announced in Feb 2016, thinking hasn't been a strong point in the British Psyche.
By that I do include both sides because the Remain campaign spent precious little time on things like the effect on EU nationals and the EU border. Instead it let Leave set the agenda whilst laughing at it. Nor did it really sell the EU.
And no one gave a thought about what would happen if God forbid they lost.
It amazes me that even now we have government MPs freely and openly without shame state they've never read the Good Friday Agreement and MPs of all stripes repeatedly demonstrate they have not got a clue what the single market is (and isn't), what the customs union is and what countries in the EEA can and can't do.
You even have MPs refering to 'Southern Ireland' or talking like the UK still has control of Dublin.
It's beyond bonkers and utterly shameful.
To me, it's one thing to have an opinion as a member of the electorate - that's fair enough. But if it's your actual job to sort out Brexit, not being an ignorant tosser should really be a job requirement. Sadly not so. Nor is there any effort to try and understand the nature of the problem at hand.
Why anyone, regardless of their remain or leave status should have any faith in the shower of shit that works at Westminster is beyond me.
Calling many of them lazy and ignorant is being charitable.
