@Glennn,
You are fixated on female genital "mutilation". And, I understand why.
Any Westerner (myself included) is going to judge this as a horrific act. We make this judgement instinctively, without even any thought. We don't know what this really entails, we don't know the differences of the practice from culture to culture. We con't understand how any mother who has undergone the practice herself then wants the same for her daughter (and yet many do). We can't even give these mothers a voice of their own... although they understand the cultural meaning behind the practice better than anyone..
What you are failing to see is how your own cultural biases prevent you from even questioning your own instinctive beliefs. And you don't see how the history of Colonization involved Western Cultural power being used to stop traditional practices it couldn't accept.
Let's say concede that female genital mutilation is unacceptable according to some universal absolute truth (rather than just our Western Cultural standards of morality).
What else from indigenous populations would you condemn? It is not just this one thing (which is admitting shocking). You want to get rid of traditional marriage. What about child rearing? Hunting rituals? Customs about aging? Political decision making?
It isn't just genital mutilation where we are imposing our values on indigenous populations. Inevitably Western Culture is going to differ in significant ways from any indigenous culture. History shows that.
When this happens, the West has always had the economic and political power. Our cultural biases, our objections, our outrage now runs the world that we dominate.
That makes what what we think a kind of truth. If you say it's true and an indigenous woman disagrees, you will win the argument and she will be silenced. That is what has happened, it is nearly impossible to find any voice expressing a disagreement with Western cultural norms such as this.
That doesn't mean anything when it comes to absolute truth.
