Re: antisemitism, just look at the antisemitic tropes in the mural that Jeremy Corbyn promoted

"Sitting around a table is a group of rotund men: one has a full beard, and is counting money. That, in and of itself, is an antisemitic symbol.
It’s not just the big, hookednoses and evil expressions that make this iconography offensive and troubling, these depictions mirror antisemitic propaganda used by Hitler and the Nazis to whip up hatred that led to the massacre of millions of Jews. This extends to the table these figures are sat at, resting on human bodies, as the Nazis also depicted.
Context here is also important. If you haven’t yet, then research The Protocols of the Elders of Zion. An entirely fabricated text printed first in Russia during the early 1900s, it purports to document a meeting of Jewish leaders setting out plans to take over the world by controlling the media and press, and fostering religious conflict to subjugate non-Jews across the globe.
There is more than a visual connection in this mural to antisemitism – the messaging is full-blown Nazi too
During the 1920s and 1930s the Protocols were a key element of the Nazi propaganda programme – at least 23 editions were published by the party in the two decades that preceded the outbreak of the second world war in 1939. The domination of the world by hooknosed men wielding power and money? There is more than a visual connection in this mural to antisemitism – the messaging is full-blown Nazi too."
FYI here is more about the Protocols of the Elders of Zion

Because the church banned usury, they got round it by Jews serving as money lenders. Hence the stereotypes of Jews as controlling the banking system
Jews are disproportionately represented in public life, and anti semitic conspiracies will seize on this as there being secret cabals of Jews plotting to take over the world
(eg 22% of Nobel laureates were Jews, although the total Jewish population comprises less than 0.2% of the world's population)
You've seen comments about Jewish nepotism even on this thread
The rise of anti semitism in the Labour party disturbs me immensely, and as a lifelong Labour voter it weighs on me heavily
