"I don't claim that Eurocentrism is solely genetic; much of it undoubtedly is caused by the experience of being colonized by the Western colonial powers creating the association of "whiteness" with power. It is on this account that I do believe that effective propaganda can significantly reduce (though not completely erase) Eurocentrism among many."
Maybe it will erase Eurocentrism, but I would argue that the drive for power itself is just as bad insofar as it helped uphold the Eurocentric hierarchy. But if you are arguing that without the colonial era (which caused Eurocentrism to begin with), this "drive" would merely be expressed in the form of raw Turanism as opposed to manifesting itself as explicit Eurocentrism, and hence "Whiteness" and those who worship it (i.e. Paleo-Gentiles) due to their genetic deference toward the progenitors of it (i.e. Giants) should be targeted first in order to end Eurocentrism, then I would agree. But Aryanization will only be complete with the phasing out of those aggressive subhuman Turanians. Non-Eurocentric, goat-sacrificing/eating aggression is also worthy of our condemnation (I would assume).
"How would we recognize present-day Zarzians? As far as I know there have been no traditional hunting clans in that region for ages."
I was thinking aggression, but since by my own admission, Bedouins are also aggressive, this would not work. So what I meant to say was that in theory there should exist very minimal Eurocentrism in this region, but now that you have clarified Eurocentrism is not purely genetic, I can see why some non-Paleo Gentiles also practice it.
"In any case, merely treating "white" strangers better than "non-white" strangers in equivalent day-to-day interactions is only one aspect of Eurocentrism. What I would consider more revealing is, for example, how such parents raise their offspring. Do they try to immerse their offspring in Western education, Western decorum, etc., believing this will 'improve' their offspring?"
I see. Now that you mention it, they are not Eurocentric in this regard. This is not to say that their parenting is Aryan (far from it) as they essentially teach their children to be aggressive playground bullies. Quite literally, my uncle remarked how the Bedouin parents would encourage their offspring to push and shove their way onto the slide at a playground, at the expense of the non-aggressive children!
Of course, if an ideological anti-Eurocentrism is also rooted in anti-Turanism, then I assume we will be able to deal with two things in one shot.
