What do you mean by "really"?
If you mean that if I go out into the world and measure savageness and emotionalness and terroristness (the freedom-hating thing is straw), I will not find an effect? This is a rather radical claim, and I would like to see such a study. My impression is that studies like that find that there are effects.
If you mean "really" to mean "genetically", note that my "weak racism" would still be a valid interpretation. (For reference, "weak racism" is the claim that whether the effect is genetic or memetic or societal only matters for what kind of intervention to fix it with, and does not have bearing on whether the effect exists or is something worth talking about.)
(the freedom-hating thing is straw)
Actually no. If one were to ask (Islamic) terrorists how they think society should be organized, one would find that their suggestions contain significantly less freedom than modern western societies.
