If one can simply make up any rights someone feels like having, even when they contradict fundamental rights (see my earlier post), I don't think they can be considered "real".

If you believe in equal rights (i.e., nobody is king of the universe) then you can't support the infringing of some people's rights for the benefit of others.

Much of the way I express myself is via the Internet. Take away my net access, and I don't have freedom of expression.

Well, at least as far as the USA is concerned, the founders enumerated the list of natural rights endowed on people by their creator. This was not arbitrary, it was based on thousands of years of western philosophy. What the original poster is worried about is the conflation of entitlements with rights.
