Corbyn explained his presence at the Memorial and his stance, but maybe you just read headlines ? Is he lying in his explanation ? What is the truth of the matter ?
Yes, he's lying and you are an idiot for believing his lies. If you go out of your way to believe the excuse it may just be that you believe less in "just one race, the human race" (which is twaddle) as you claim.
You are clutching at straws trying to come up with excuses for dispicable behavior. Why? You have a motivation for doing that and the only one I can think of is that you prefer jew-murdering terrorists to jews. Which suggests you are anti-semitic.
Or maybe you're just easily taken in.
Or just admit that Corbyn's actions are anti semitic and he should be booted out of his political party, certainly not given the leadership position. The fact that he is leader suggests that anti-semitism is systemic in the labor party and the left.
