Brexit has been a political disaster. Constantly rehashing the debate almost one year on is precisely why. I have watched on in despair as I have seen good centrist people move further and further into the arms of the conservative party. When you imply people are idiots or stoopid racists they don't come over to your side they go wherever they are valued.
Brexit has let the bourgeois leftist cat out the bag. Tim Farron, Blairites, the Guardian, the Independent. Elitism and hatred is pouring out of the megaphone. The echo chamber is preventing self-awareness and leading to self-defeating beliefs such as that Brexiteers are bogeymen and that Brexit can be stopped.
It's a gift to Theresa May who just had to do a slight centrist virtue signal to clean up. May gets to allow Farage and UKIP to be the Brexit extremists who piss borderline people off instead of her party. Whilst labour and Lib dems have remain extremists within their parties sending those borderline voters right into Mays arms.
