Join the chosen few

Here's Jeffrey Goldberg, commenting on his indifference to the ridiculous assertion by The Daily Telegraph that Ahmadinejad is Jewish, laying out his perspective on Jewish self-hatred:

Jewish self-hatred is an entirely predictable phenomenon. It ain't easy being Jewish.... Some Jews, the weaker ones, adopt the culture and outlook of their oppressors. Some do it sincerely, because they have internalized the anti-Semitic calumnies hurled at them, and others do it for cynical reasons, such as career advancement. Others do it because they are scared, and so assume that associating themselves with anti-Semites will afford them some kind of protection.

Which really only makes me wonder - which of these explains the concept of the RJC? Not that the reasons need to be exclusive.
