Indeed fellow American anon. What you are witnessing, what the Europoors call "Banter" is really just their form of insecure bullying. It is what lead to the first world war and what was directly responsible for the second World War. You see Europeons cannot let anything go, they can't live and let live. Much like a retarded school yard bully they simply push until their victim snaps and starts a war. The most recent and obvious example being Germany after the other Europeans kept kicking them while they were down despite the USA telling them to cut it out. Then once Germany got back on its feet they declared themselves the best Europeens in a fit of butthurt rage and declared war on the world. A costly war that could have been easily avoided if all parties involved had simply treated each other with common decency. 

If you have ever had the misfortune of interacting with a Euro in real life they are far and away the rudest people you will encounter. Not even American blacks are as bad as them. Because if the American Negro is sated of his blood lust and greed for the moment he will go about his business without causing a ruckus. Eurotrash on the other hand will engage in "banter" no matter what the circumstance and even when it is against their interests to do so. You could be pointing a gun at them and be livid with anger and this would not dissuade them from angering you further.

In short, bullying is the default Euro attitude because they are lowly idiotic creatures who masochistically love to start fights even when it is uncalled for. Ironically, because they are cucks this attitude is only extended to their fellow whites as being rude or violent towards a non-white is considered the most grave of offenses to the Eurocuck.
