What's the problem here? What better way to understand "your own culture" then by learning about others'? And just what is "your own culture" anyway, now of all times, and especially "American culture", one of the most diverse and multi-culturally defined cultures in the industrialized world? These distinctions are becoming increasingly trivial. In our increasingly globalized world, global-culture is of increasing influence, and there are only gonna be more people like you and me to espouse it.
