How rude!
With regards to the topic at hand, Dominance and submission are facets of everyday life - animal or human. Animals are merely more open about it. As I said in another (albeit related) forum, pack animals have clearly defined hierarchies ... homo sapiens sapiens is, at heart, a pack animal. Alpha males and alpha females are as commonplace in our society as they are in feline, canine, lupine, leonine, etc. It's called "survival" and passing along genetic traits.
Unfortunately, rudeness is a learned behaviour common in naked apes.
