I strongly disagree. Marxism is so toxic precisely because it destroys identity. This is also why the Kalegi plan prioritized breaking down shared identity. The idea was to destroy public cohesion so master class with a strong in-group preference could rule them!

In-group preference long predates marxism. It's the wellspring of the nation-state, and for good reasons. National identity is a source of strength.

Does Jewish nepotism in hollywood imply their role in the film industry would be stronger if they stopped preferring other jews? Is it a bad thing? I would argue this is a good thing on their part. By the same token, are the Swedes are better off because their regimes chose not to prefer their own people over migrants? I have a very hard time seeing how that would be the case.
