Aquinas and Inculturation

See this article:

Aquinas in Africa by Thomas O'Meara O.P. from a recent issue of America.

An interesting article, but again the author falls in the more "optimistic" wing of theologians when it comes to the ability of Christianity to adapt to local cultures. While I would agree, along with scholastic theology, that the thing is received according to the mode of the receiver, is it possible that many advocates of inculturation overlook the drastic effects of man's fallen nature when it comes to culture? Is an African drum circle just as sacred as a Bach cantata? It is not as easy to answer as we would like to think.
