I have said this before in regards to Wilders, but it bears repeating. To an American's ears, it is an uncomfortable thought saying that Western civilization is superior to other civilizations. In America, the popular academic trend is what we term, Post-Colonial thought, which basically bashes Western Civilization as a historic oppressor while maintaining that all cultures are equal. Multi-culturalism-spelled with a capital M is part and parcel of that ideology.
Personally, I don't think that Western civilization is better than say, Japanese civilization, which, in my view, the Japanese people are amply demonstrating in the face of their recent catastrophe. We could learn a lesson in civics from the Japanese. On the other hand, is Japanese culture superior to the culture of the head-hunters of Borneo? Of course. As for comparing all the rest, I'll leave that to you the reader and Wilders.
