Basically the "Culture" as you put it, consists of many many subcultures. You have your average "In it for the yiff" furries (AKA, the FURverts), your Fantasy Role-Play furries, your babyfurs, your talented authors and writers of the aforementioned sub-groups, and of course you have your trolls, just like any other community.
Not all furries like biting, and I admit I'm not much into it, but I like to role-play it on occasion.
And there are many furs that defy classification, much like in the real world.
Yet despite our diversity, we're the Internet's most common community punching-bag.
