While her belief in female circumcision may be misplaced, her intention seems to be that other cultures are not qualitatively better or worse. You, on the other hand, seem to genuinely think that we can evaluate different cultures, eventually ranking them in terms of "best" to "worst." This is untrue.
Cultural relativism shouldn't be an excuse for blindly participating in cultural practices; but these practices aren't to be condemned or abandoned specifically due to their cultural worth, nor should we extend the scientific research on certain practices to evaluative judgments on whether or not a culture is "good" or "bad." Cultural relativism means refraining from qualifying another culture as definitively worse than our own. Good, bad, better, worse, etc. are terms that can only be weighed from within a cultural framework. Female circumcision might be a scientifically unhealthy practice, but this doesn't mean that a culture that practices it is definitively worse for someone born into that culture than, say, Western liberal democracy would be.
I'm sure I've criticised cultural relativism some time before on here. The last time I kind of got the same response, a definition of the concept with the implication that I didn't have an understanding of it.
I really don't see why cultural relativism is so widely accepted among people. It satiates people with insecure identities that relate to say, post-colonial nationalism or their religious identity. I don't think it does much in the way of good though, or at least other than that, if you regard that as being particularly important.
I want to respond with quotes and my comments because it would take me time to summarise the same point I'm about to make.
Bernays:
""There is no word in the English language," it says, "whose meaning has been so sadly distorted as
the word 'propaganda.' The change took place mainly during the late war when the term took on a
decidedly sinister complexion.
"If you turn to the Standard Dictionary, you will find that the word was applied to a congregation or society of cardinals for the care and oversight of foreign missions which was instituted at Rome in
the year 1627. It was applied also to the College of the Propaganda at Rome that was founded by Pope Urban VIII, for the education of the missionary priests. Hence, in later years the word came to be applied to any institution or scheme for propagating a doctrine or system."
"The conscious and intelligent manipulation of the organized habits and opinions of the masses is an
important element in democratic society. Those who manipulate this unseen mechanism of society constitute an invisible government which is the true ruling power of our country. We are governed, our minds are molded, our tastes formed, our ideas suggested, largely by men we have never heard of. This is a logical result of the way in which our democratic society is organized. Vast numbers of human beings must cooperate in this manner if they are to live together as a smoothly functioning society."
Bernays, E, 1928
Now, as for Western universalism, is this really a 'problem' as such, or is it really a sign of the times and arguably a great accomplishment?
To quote:
"Our time is the first in which it has been possible to take a literally universal view of human history, because this is the first time in which the whole human race, all round the globe, has come within sight of coalescing into a single society." He goes on to mention this situation's precedents, through historical unification through Empire. "The issue between universalism and nationalism is one of life and death for the human race."
Arnold Toynbee, 1963
Now, I think I have brought some backing for at two proposals. First, that culture, popular opinion and political trends in a country are ultimately decided by an elite few. Whilst showing respect for those opinions and cultural trends (say the rise of Islamism after a few decades of flirting with secularism or something) might, on the surface, appear to be a benevolent decision, I would argue that it is most directly beneficial to the ruling elite in the country, both the official political elite and perhaps religious elite but also the more veiled sources of influence.
As the countries we call the West moved away from dogma, authoritarianism and made economic progress, the culture definitely changed. Witches are no longer killed by fire and women aren't dunked in lakes for gossiping. The Catholic Church has lost large amounts of its power and influence in various parts of the West and ultimately this is deemed to be good by progressives.
Now, view these changes from the point of view of an Islamist, they weren't truly positive changes. More to the point, they probably aren't from the point of view of someone living in Byzantium, if they could see the West today. There isn't a small reservation were nazis are allowed to kill a quota of Jews and Roma to satiate their fury and preserve their cultural integrity and Germanic pride.
