Treat it as "unreliable narrator". I enjoyed it as a story, without taking too seriously any of the opinions which are put into the mouth of the main character (or... either of the main characters, if you prefer). I'd put it on the "To Read When You're Eighteen, So You Can Reread It When You're Twenty-Five And See How Much You've Changed" list. Along with most of Ayn Rand and Nietzsche.
