Thanks for a very useful analytical tool.
Some time ago I developed a model of the political process as a collection of encompassing spheres, based on the definition of that process as 'the process of effecting choices for the community as a whole' (which communities, like individuals, have no choice but to do).
The inner sphere of the political process is the political system: the set of institutions in which choices for the community are effected. It encompasses government, as the functional core of the political process, but it extends beyond it to include other organizations as well as political rights and 'foundational documents', such as a constitution.
Beyond the political system is the realm of political speech: speech related to effecting a particular choice for the community as a whole. That makes political speech something more than a right.
Seeing political speech (and the political process) that way also resolves the issue of self-reference for a democratic political process: political speech exists as the means of establishing a democratic political system without the existence of a ‘right’ of freedom of political speech.
It implies, further, that the prime condition for 'nation-building' must be the existence of freedom of political speech. The colonists in this part of the world had the benefit of such a state of affairs leading up to their Declaration of Independence.
