I have to disagree with the statement that most people don't read the texts literally -- at least not the Muslims I know. The main problem is, as others mentioned, depending on the context and history, certain verses could be literal or symbolic. So mainstream religious folks usually don't have the time and knowledge to decipher all the intricacies. Now this may or may not make them fundamentalists. But it is easy to go for the literal interpretation which usually provided by religious leaders. Verse 3:7 (Surah Al-Imran) in Quran is a good example.
