Who are we to say “our culture is best”?
It is extreme arrogance and even racist to consider Western civilization superior to others.
Bullshit. Western civilization, or at least American civilization, is superior to others, at least inasmuch as We, the People have established Freedom and Justice a under a Constitution which helps preserve it.
Civilizations which are less free, either in reality or on paper, are inferior, IMHO.
And that observation, my friend, is neither arrogant nor racist. It is simply a cold, hard fact.
