Unsurprisingly, you miss the point. The anti-semitism meme is based on a transparent lie that Corbyn is a threat to British Jews. Many British Jews beg to differ, and have stood up to be counted as Jews to help expose the lie. Were it not for the magnitude and mendacity of this campaign to prevent an anti-neoliberal, pro-Palestinian politician from becoming PM, none of them would have bothered pointing out their own ethnicity.
