Yup. Frequently conveniently forgotten by the "if we hadn'ta saved yer ass, yew'd be speakin' GERMAN" crowd.
My sentiments exactly.
I love America. Seriously I do. But all the flag-waving and big "we're number one" foam finger bullshit was a real downer for me.
I no longer live in the United States, so I won't presume to give you any advice on immigrating, but as you are a British national, I might suggest you try Canada first. It has most of the advantages of the United States, with far fewer of the more distasteful attributes of either your home country or mine.
Unless you absolutely cannot survive without owning a military assault rifle and several cases of ammunition, are deeply religious and/or fanatical about American football, or have a medical condition which requires you to live in a Mediterranean or subtropical climate, you really wouldn't be missing much by going to the "other" America instead.
