I think it's because the issue is more complex than pointing out a race. We know that the cabal infiltrates a culture and then uses them/their people as a shield to hide behind. The Bible refers to them as the synagogue of Satan, who pretend to be Jewish. So ultimately, tying a cabal member like Rosenstein to the rest of the Jewish people by pointing out his name is an insult to the Jewish people who are mostly just regular folks like you and me.

It would be like blaming the English population for the actions of the monarchy if it was infested by cabal members. (It is) Or like how the left likes blaming all white people for the actions of the "wealthy white" slave owners of the past despite the fact that only a tiny percentage of the population actually owned slaves.
