"Pushing the meme that you need a lot of Jews, specifically Jews, to validate Corbyn as not "anti-semitic" is however a racist* view because it privileges one group's views on an ethnic basis"
It does not give them privilege, it merely points out that Corbyn is not a threat to British Jews generally. Those Jews claiming a 'threat' from Corbyn are given privilege in the media; other Jews coming forward to deny the threat exists are entitled to make their own voice heard. It's absurd to accuse anyone passing this on of 'racist' anything.
