I'm from the UK. My country seems to generally dislike America. it might be because our country used to be America's *****. you know, the one who got slugged and promptly yelled "thank you sir may I have another" from the kitchen floor while fetching them a beer and making them pancakes every day. It might also be because we got dragged into the Iraq 'war' by them. Oh well.
Personally, I don't hate America at all. In fact, I recognize it as the powerhouse driving force behind most things that it is. Movies, TV shows, games. all that good stuff, America is where it all gets decided. In fact I want to move there in the future, and fully intend to once I finish or leave/get thrown out of my Uni course here.
I just make fun of it cause it's a pretty easy target. There's SO many stereotypes to play on, plus there USED to be the millions of jokes you could effortlessly make about George Dubya.
