For example, in your essay you wrote that we should defend individual rights not by a bill of rights but through the free press. How will you protect the right to a free press without a bill which establishes that right?
If you read the whole thing, it's about having a Constitution which guarantees the proper practices of a Democratic / proper Republic debate.
You call a writ of rights 'ivory tower' because it does not conform to the whims of the zeitgeist.
No, but because it does not bend to common sense or scientific data which proves one 'right' might actually be impacting on another more important 'right' significantly. In other words, as long as we leave these wonderful words like 'Right to privacy' and 'Right to life' up in the air with the Ivory Tower, congratulations! No one is going to disagree! Pass the champagne. But once we ask whether RBT is a worthy, temporary suspension of our 'Right to privacy' so that we can live in a society with a whole lot more 'Right to life', and that scientific studies prove this, well, then things get more complicated don't they?
However, while times change human nature does not.
No, but the drugs, guns, and cars those humans use do change. Your use of your drugs and car might just MASSIVELY impact on my 'right to life'. So your 'right to privacy' might just need to take a hit for 3 minutes a year in an RBT.
Hence, human rights do not really change.
If your Founding Father's got it so right the first time, why are so many of your rights
amendments? They're so universal and so eternal that they... oh, just remembered the 'right to bear arms' later on. And then had to add other ones. And others. Which were expressions of the concerns of the time. Which basically reflected the Zeitgeist of the time.
But hey? They're eternal right. They know how to create laws for RBT's to protect my right to life, don't they? Well, don't they? They just KNEW we were all going to be driving cars back then? They had to! They were creating laws for all time!
So today you send a text message instead of a telegram; big deal. Does that make tyranny suddenly OK?
It's a big jump from cops being able to pull over someone texting while driving to tyranny. It's a big jump from an RBT to tyranny. Try asking some American friends who live in Australia. They might actually say it's a nice place!

I'm not talking about tyranny. I'm arguing that the best way to guarantee human rights is through the public discourse and procedures of a proper constitutional democracy/republic.
Any evil can be justified in the name of 'the greater good'.
I know. RBT's are
so evil. I mean, I've blown into one every few years: I must be the anti-Christ by now!
Democracy sucks; individualism wins. Long live the Republic!
Individualism sucks and creates a selfish society dedicated to ME first and ends up murdering 4 times as many people (on a per-capita basis), because American's have a 'right' to bear arms!
Long live DEMOCRACY!
