I disagree. From a gameplay standpoint, it creates an interesting strategic decision: Do I keep this enemy temple for the bonuses and take the culture penalty? Or do I raze it and build one of my temples?

From a roleplaying standpoint (for lack of a better word), it simulates that way that a native people who were skilled in, say, archery, could retain those traits that made them good archers under a different country's rule, provided their culture wasn't completely obliterated. By destroying a conquered enemy's temples and building your own, what you are really doing is suppressing their religion and culture and replacing it with your own.
