Starker is a joke.
False Anti-Semitic accusations have become the right-wing's favorite tool to deflect any criticism of Israel while bringing down people they see as dangerous to their economic interests. Shame you're disseminating the memes here, but unsurprising. And I'll keep informing people about the real story behind the falsehoods as long as I keep seeing them posted.
Multiple Labor Party politicians dealt in anti-Semitism very casually. While Corbyn largely avoided direct or strong anti-Semitism himself, his casual reaction to it - and several times his “nuanced” defense of those guilty of anti-Semitism - showed shocking insensitivity about a pretty important issue. The denial of all accusations of anti-Semitism by many leftists is pretty amazing from people who pride themselves on having a moral high ground.
