Jewish men are notoriously effeminate. They seem to compensate for this either by mocking/degrading the concept of masculinity (as this article does) or fantasise about it, like they do with Superman and other comic-book heroes. They want something they just don't possess, so they deal with it by deriding it and fantasising about it.

Turning white men into effeminate creatures also seems to be related to this. Just like Jewish women have sought to shape white women to be more like themselves in behaviour (hawkish/overbearing/promiscuous etc - all the stereotypes of Jewish women).

It's no coincidence that white people in the West today have become more like the stereotypes of Jews of old.
