I must say, seeing as we probably have the biggest population for a first world country, we definitely have a bigger chance of having much more stupid people. As opposed to places like the UK who only have a total land area of (according to wikipedia)243,610 km2 vs America, which has a total area of 9,826,675 km2 (nearly 40 time bigger).
I don't think the hate is undeserved, though. But I mean do you guys really think yourself so high and mighty that you don't succumb to stereotypes?
(This is an example, bear with me. It will all make sense in the end)
Hey england, what's with you guys and your incredible hatred of the letter H? Can't you freaking start a word without dropping the H? I mean, half the people of your country can't even say Harry Potter, your national hero. Who's Arry Potter? I've never heard of him. And why do you replace "TH's" with "F's"? You guys can barely speak your own language, it's ridiculous. And nice dental plan you have there. Do you guys just have trouble sipping tea through straight, white teeth?
see? I know for a fact that not everyone speaks in a cockney accent, or has bad teeth. But when I present the stereotype like that, it sounds incredibly douchey.
I promise you that Americans would not make fun of the English if they did the same in return. Pinky promise.
