Genetic differences are FACTS. If you do not account for facts, you're operating in the twilight zone.

It does not, however, follow that all perceived differences in behavior between gender groups are genetic at root. It would be rather dishonest of me to say "men in the US like trucks, therefore liking trucks is embedded in the male geneome" without considering that there could be a societal aspect to that behavior.

Genetic differences may be facts, but blindly assigning genetic causation to perceived behavior without completely ruling out other possible influencing factors is just bad science.

Seems like the Muslims have taken up the Evil Baton.

That said, what if the Jews had been the outgroup that has no obligations to the ingroup and vice versa? In the Middle Ages there were prohibitions on taking interest and charity was encouraged, which meant credit was unavailable, but relatives had potential to be bottomless barrels. We are still seeing this with athletes from an impoverished background. One can see why a group with no such restrictions would be useful, even successful.

I think in East Africa the Indians occupied a similar position in society, and when Idi Amin emulated the Catholic Majesties and expelled the Indians the outcome was equally disastrous.
