Presentation effects everything you show to me, including cultures.

As is often my wont, I spent a few minutes having a think about aspects of my situation. That means every part of it, including the things I use to distract myself from it. And after one minor crap-exchange during a World Of Warcraft dungeon run with a very ignorant person that I and my party-mate of preference both disliked, I began to think to myself. What do the cultures that other people partake of look like to me, and why?
