You know, you can believe what you want to believe but this narrative that has built up over the years isn't one that I personally recognise.
During the Miner's Strike, I knew alot of people (1 or 2 intimately

) who were hard left as I spent alot of time on picket lines and collecting. First and foremost, these were 'Labour people'. Obviously at that time, they felt betrayed that Kinnock's Labour didn't come out in support of the strike (which did beggar belief at the time) and merely wanted to influence Labour back to its traditional roots. This was a time when 'socialist' hadn't been coined as an insult by right wing media. The Labour leadership did seek to demonise these people owing to their criticism of them over not supporting the strike ... and, of course, gained traction over the whole Hatton thing.
As an example, by no stretch of the imagination was Scargill an 'entryist' and yet the 'broad church' of the Labour party started treating him like a bad smell.
As I say, I find it difficult to buy into narratives on Labour. I struggle with the idea that Labour is ingrained with anti-Semitism which seems to be received wisdom now. I'm not saying that there isn't truth in it, but it is hard to reconcile with the hard fact that their last elected leader was jewish (although that seems to have been conveniently 'forgotten' now).
