My fellow Leave voters, did you vote Labour in 1983?
Or (like me) would you have done so, if you had been old enough?
Or would you have done so, if you had been born?
Do you regret that Labour lost the 1983 General Election?
If your answer is no, then you have absolutely no credibility whatever.
If you were old enough to vote Labour in 1983, but you didn't, then you just need to shut up and go away.
