The OP shows an interview with one of the Labour Jews who still support Corbyn and deny that Labour has become more anti-Semitic.
He is in a minority, and Corbyn himself now admits that a problem has arisen.

I am astonished that people here deny the anti-Semitism in the mural.
Corbyn is unequivocal that it is.
"I sincerely regret that I did not look more closely at the image I was commenting on, the contents of which are deeply disturbing and anti-Semitic."

ITV and BBC both acknowledge it and warn they are going to show it.
Can anyone find any mainstream media organ or commentator who defends it as people here have.

It proves that you do not recognise genuine anti-Semitism when you see it.

Guardian editorial,
" The mural in east London featuring anti-Semitic tropes that sparked the protests should, at any time, have been met with unqualified repudiation."

"That two Jewish community organisations – the Board of Deputies and the Jewish Leadership Council – have written in the strongest terms and taken to the streets is a sign not of obsession or partisanship but of fear and desperation."

" It does not make the issue minor. Under Mr Corbyn, Labour has not been quick, clear or uncompromising enough to deal with those shameful remaining pockets."

Corbyn, "We recognise that antisemitism has occurred in pockets within the Labour Party, causing pain and hurt to our Jewish community in the Labour Party and the rest of the country. I am sincerely sorry for the pain which has been caused."
