My eyes are fine, I think that brexiteers were doom mongers. The leave camp was fuelled by irrational fear, hatred and of course lies. No point in digging up a corpse but 'project fear' was just another silly phrase that ignored warnings that are as accurate now as they were then. History informs that overwhelming propaganda on social media engineered by our enemies was successful in influencing the ignorant masses.
I invite you to answer your own questions. You may discover that cognitive bias remains the only enemy now.
Have you noticed that after several investigations by pro-Remain authorities, no one has been able to prove that the leave campaign did “irrational fear, hatred and of course lies”? Maybe that’s another example of where Remain and Remainers failed.
For me, ”Leave” was about hope, confidence and friendliness. We can stand on our own feet, we can try for something better, we can embrace the world.
But you also highlight yet another destructive Remain behaviour: a belief that Leavers are ignorant mindless gullible drones who swallow whatever bullplop is placed in front of them.
What makes you think Leavers lacked the ability to analyse conflicting range of opinions, spin and expert views, and draw their own conclusions? The fact that they came to a different conclusion for you doesn’t make them ignorant.
Maybe you (and other Remainers) failed because you lacked access to the entirety of their data (e.g. life experience). Maybe you (and other Remainers) failed because you failed to get your data into their calculations?
