Isn't easy being an American traveling the world.
Ever been to Cuba?
Didnt think so.
Also the answer some of the questions.
I myself do not hate America, but a lot of countries dislike Americans because of how the propose themselves to other nations. I will give you an example, on a trip to England I was in front of a "queue" of American girls who said, "why is it called a queue? That is stupid", to everyone around them. Like wtf? It is this, "It has to be America's way FUCK YEAH or it isnt right or something".
Countries also dont like being told "democracy" is the best form of government, or being invaded and being forced to adapted to democracy. Let countries form their own government and how it has always been for thousands of years.
Or the arrogance factor, especially being #1 in everything, because everyone knows America is number 1 in everything.
Or finally, the drug issue. Everyone in Canada knows that marijuana would be legal if the American government would stop putting pressure on the Canadian government. But Canadians have to force drug laws not to ruin relations.
