It depends on if you're using the left's own reasoning or not. If you are, then the idea of one group being "statistically intelligent and productive" is absolutely not acceptable, and the only acceptable explanation is that their success is due to massive discrimination against others. You know, the way they reason about whites. That's the point, that everything they say about whites, which they then use to justify racism against whites, applies even more so to Jews, but they'll never accept that simple argument because they hate the conclusion.
