How do all europeans hate americans?

They don't - you've bought into the sound-bite lies - most remember what America did for them in the past, still do, and are forever grateful - check with the Leaders of Italy, Germany, France, United Kingdom, etc, they're pro-American and have stated so.

cause americans think that there better then in the rest of the world evan though its unconcience the rest of the world notices it

Most Europeans don't hate Americans.
You just need to talk to people that still remember the times of World War 2 and so forth.

When I lived in Europe, I found that every time a car drove by that threw trash on the road, it was americans. Every time I was eating at a restaurant and there was a table of people talking so loudly that you couldn't hear your friends, it was americans. Every time I heard LOUD complaining about ANYTHING, it was americans.
Not every American is rude, loud and obnoxious but many are and the europeans tend to grow VERY tired of the attitude. And this doesn't even cover the attitude of our politicians...

When you add a national leader that manhandles female heads of state, a foreign policy that only rights injustices in countries with oil reserves (and badly, at that), and a populace that swaggers with arrogance despite being some of the most uneducated, unhealthy, murderous rednecks in the free world, I think it's frankly amazing Americans aren't simply turned away at airports.

Not all europeans hate americans. But most of them strongly dislike the average stereotypical american, who are loud, lazy, obnoxious, insolent, arrogant, prudes. These are the same americans who go to a foreign country and go to McDonalds instead of trying out the local food. Of course, its all based on first impressions, some will give you a chance to prove yourself, some are just as bad as the stereotypical american.

But they do have a point when disliking us about our President, when he gets elected and makes such poor decisions about foreign policy without major public backlash by the majority of the population.

Probably something to do with World War 2.. It always is basically :[ But I'm part of Europe I like Americans :]

Try this as an experiment when you travel in Europe: For a while, tell people you're Canadian and see how they treat you. I think you'll find Europeans will accept you more as a fellow member of the planet Earth, rather than as someone who thinks he owns the planet.
