They are decent people.

However, they are infected with a type of anti-Semitism that they cannot even recognize.

It goes like this.

Here are some facts about ways that the lives of people in Gaza could be better and are not and that Israel imposed. Therefore, what are we, UNHRC workers supposed to do? Keep silent just because Israel is Jewish?

It is a type of argumentation that does not resonate in other conflicts. Basically, the “logic” sounds logical only because of the world’s history of anti-Semitism. The UNHRC workers are arguing that that history cannot stop them from righting wrongs.

What they ignore is the fact that that very logic causes them:

a) to apply double-standards to Israel, lest they “keep silent just because Israel is Jewish.”
b) ignore much worse (and less justifiable and defense-related) actions by other countries because the UNHRC doesn’t need to prove in those cases that they will not be kept silent.

To see point (b), just imagine how much sense it would make for them to say “what do you expect me to do? Keep silent just to prove I am not anti-Arab.” It just doesn’t make any sense. So they don’t need to “not keep silent” when the Arabs behave inhumanely. They can keep silent. And do.
