Patriotism in Unites States is wrong. It is blind devotion to the state. If the government is worshiped and its actions go unquestioned then the patriotic become puppets of the government. This blind devotion to the state occurred during the National Socialist movement in Germany.
What one should love is "freedom" or "liberty" and not a government. The United States government was created in order to provide liberty to its inhabitants. It is just a tool and a means to have and maintain liberty. If it does not fulfill these ends then it does not deserve our love. This is of course stated in "The Declaration of Independence" when it says that Governments are created by us in order to maintain the God-given rights of Life, Liberty, and the pursuit of Happiness. And if any Government does not provide these things for all its citizens, it is the Right of the citizens to remove it and install a new government.
Excerpt from The Declaration of Independence:
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."
