Thank you for the reply. Very good post, although I would argue against the calling of the English Bill of Rights as immature in parts. I think its a better and more rounded document than that. Also Scotland also has a Bill of Rights. The US BoR was influenced by both.
That said, the idea that only Protestants have the right to keep and bear arms, or that only MP's have an absolute right to free speech or to petition for a redress of grievances are -- in the sense that they are not fully developed ideas -- immature.
