I didn’t blame “the left” for Brexit. I blamed “the left” of the Labour Party for facilitating Brexit by putting up a shit candidate for Prime Minister, and surrounding him with shit people. This is what allowed a charlatan to take power. I didn’t take them to task for it at the time or rant about it. I gave them my vote.
But now they need to shut up and let Labour reinvent itself into an electable party. The dissenters at the conference are loons for not doing that. My point is that simple and I don’t really need the political history details because I know them: sensible politicians were and are pro EU, daft ones were and are anti EU, from all parties.
