Steve,
So what are YOUR personal experiences of antisemitism in Labour that make you qualified to tell me who's more informed than whom?

Well Steve, you have been a member for a few months, and the people I have been quoting have been working in the Party for most or all of their adult lives.
I do not dismiss people's views because you claim they are Israel apologists, which you refuse to justify, and which is anyway a non sequitur.
