My experience is that the "BP culture" is as varied and diverse as any culture can be. Owning BP's doesn't change your beliefs or your taste in movies. Having a bunch can certainly affect your schedule.

I will say that there are things that are very indicative of "Reptile Culture" as a whole. A better understanding of the animals for one thing causes you to watch nature shows more critically. Most Reptile people crucify Animal Planet for instance.
