The dictionary defines patriotism as "Love of and devotion to one's country." There is a few words missing here that could easily be assumed, "as is." So for argument sake let's say patriotism is "Love of and devotion to one's country as is."
So if you try to change your country, then it could be considered unpatriotic. The patriot act is, in fact, unpatriotic.
Now let's not assume the "as is" part. It makes sense, to liberals especially, that if something is wrong with the country, you try to change it. The first step in changing it is admitting that there is a problem. We call that criticism. So it's not fair to accuse liberals of being unpatriotic for criticizing their country.
So the word is interchangeable. Either side can accuse either side of being unpatriotic unless they are advocating the status quo. Advocating the status quo is conservatism in a nutshell.
Why aren't conservatives either outraged over the patriot act, or more understanding of why liberals are?
