With powerful Brexit fuelled nationalism I am not sure that direct action will achieve much. Boris’ ratings are probably sky high because Jo Public thinks he will get Brexit done and can’t see that the emperor has no clothes. After all he has battled the virus personally.
As to the Labour party, I rejoined after having left with the Iraq war and have considered leaving. But that would weaken the left of party, there is still hope that Starmer, who was after all in the Corbyn cabinet as a key figure, may not purge the new members and that the new members may still keep the party from straying back to Blairism. I thought of resigning but am holding off for the time being.
