Not that it matters, really

It matters a whole lot actually. Its trying to attach a murdered man's name to your lies to try and leverage the indignation about his death for your cause. Its morally disgusting and abhorrent in every way.

Whatever his true feelings about Israel are are that and whatever words he said are what we have, and if they aren't enough to whip up your cause then you should work on building it up yourself instead of using the dead, who can't defend themselves against your manipulations, to do it for you.
