"Problem with that stu is now you put in the hands of whatever elected people incredible power like passing a law to limit your free speech or press."

Except in practice it doesn't work like that, not here in the UK at least. For example, we argue about the bias of our broadcast media and each side thinks it's biased against them, which means in practice it's probably relatively balanced. It's because the public are so vociferous about broadcast media bias that any bias is called out immediately: a positive for social media.

An unwritten constitution means society operates under a broad consensus unencumbered by the dogma of a document written by people long dead who could not have imagined the world we live in today. This consensus isn't perfect and a glance below the line here on Mudcat shows how UK folk discuss, debate and argue (sometimes very robustly, sometimes poorly) constantly but that is in a way a microcosm of the way our society works.
