By the way, from what I have seen, when most Americans say Europe on the internets, they don't think it's a single country, but rather they use it to refer to Britain.
It might be because if you speak English they will assume you're from Britain.
To the other Europeans: The US is about as diverse as Europe so saying "in America" makes just as little sense as saying "in Europe" regardless if one is legally a nation while the other is not.
