Do you agree with Obama that his "Church" is diverse?

In his statement in which he predictably says he does not agree with his Pastor and mentor's angry views, Obama says that his Church is "diverse." The church's web site says they are "unashamadely black" and every time I see the Church congregation, I see only blacks - how could it be that a Democratic Presidential nominee doesn't know what the word diverse means? Or do you think he said it only because he doesn't want people thinking it is a black supremacy church?
