We are always having to adjudicate the boundaries of rights... that is why we have a court system. Where those boundaries are IS up to date, and has changed over time... this is unavoidable, because there is no 'natural' place to put those boundaries.
Questionable. Who says you have those rights? The government. They can take them away at any time. Just look at the USA PATRIOT Act.
Yeah, but he enacts the will of the majority ;)
I totally get & agree with the sentiment, but not in the absolutist form. It's always going to be fuzzy, the question is mostly how we weigh the needs of the many and the needs of the few (or the individual). I do believe that the average response to that is strongly reflected in each nation's laws & culture, with the US emphasizing the individual's needs a lot more.
