Thanks. Fortunately, in collaboration liberalism and technological advance avoid some of the pitfalls you talk about. I agree that liberalism isn't practiced widely enough or honestly enough, but this isn't a fault with liberalism. The cultural diversity argument is weak. From a pragmatic viewpoint, if this diversity was imperative to survival then it would itself survive the influence of other culture. Secondly, culture can and is incorporated (albeit selectively although this may be a good thing) into rapidly developing cultures. If cultural homogeneity means we lose cannibalism, ritual and religious mutilation and millions of children dying to smoke inhalation each year then I can live with that. I think the good and distinct components of undeveloped cultures will be embraced by developed cultures and cherished by the developing cultures themselves.
