if you care about freedom and liberty.
Yes I do. The thing "the US" doesn't get IMHO is that a person's freedom ends where another's begins. It's too easy building your citizens' freedom at the expense of other peoples'.
Mind you: I'd be equally critic if this were to be the position of the EU or whatever else. It's just that these kind of things generally come always from the US (ACTA, SWIFT, etc.) - so I get started up pretty easily when somebody links "freedom" and "US".
And BTW, I disagree with the primadonna view of the US: no, you're not strictly needed. Simlarly, the EU is not strictly needed, Japan is not strictly needed, China isn't either and so is India. Nobody's strictly needed.
