Nearly all of the statements and actions in issue with Corbyn have nothing whatsoever to do with Israel. 99.9999% politicians manage to avoid antisemitic murals and endorsing antisemitic books just fine.
It's not remotely difficult, and I'm sure 99.999999% of Labour Leftists with nigh-identical positions would not be so compromised. Can't understand why the Labour Left had to (politically) die on that hill.
The book was presumably "Imperialism: A Study" - not wholly about Jews, and Corbyn describes the accusation as "mischievous representation".
These are weak examples, basically a degrees-of-separation argument coupled with your own opinion of what is black-and-white anti-Semitic without informed discussion (or even examples since you only provide suggestive anecdotes, not sources). Feel free to demonstrate your "99.9..%" numbers for politicians that are under the same amount of scrutiny.
