I see the point you’re making although I think it’s twisting his words a bit to suit the Antisemitic theme.
If someone said this in reference to Salisbury then I doubt anyone would mind:
“Russian people with any sense of humanity need to start speaking out publicly against the ruthless murdering being carried out by the Russian state!”
Russian isn't a race or religion, but let's take that example and say they were - it'd be wrong because Russians are entitled to form an independent thought and not be dismissed as lacking humanity if they did.
It's straight up anti-Semitism by definition, there's no way to sugarcoat it. It doesn't matter what your view on Israel is; you should be able to separate the nation from the religion.
