Is this a fair thing to say?
For starters the Magna Carta was a transfer of wealth and power from king to barons. Whence democracy?
If you actually bother to read it, as most historians have not evidently, you will see it calling for Jews to be stripped of their assets and for whites to be given them. Whence democracy.
The barons then are the wealthy and powerful today just like then. Nothing important has changed then. Whence democracy?
OK so we have democracy today. And whence justice?
The law set in concrete at Runnymead is not in and of itself justice. Yet it's the law we still have today.
