If you can't read the founding documents in their original language, if you can't read and comprehend the philosophy behind them, if you can't viscerally understand the grievances against the Crown (and the bases for those), you are going to have a very difficult time understanding what America is, is supposed to be , and what it is not.
If you want to become an American, it's more than a new label on the outside, there is some content involved, too. That doesn't mean you can't keep cooking goulash, or wearing a kilt, or celebrating some holiday or another, but realize that is your past heritage, the future is here.
