"is a sacred document, akin to the Magna Charta (sic)"

The Magna Carta is far from being a sacred document; it was a bunch of toffs protecting their own interests from the monarchy. Why it's touted as some sort of milestone in the freedom of ordinary folk is beyond me: it's the aristocracy making sure they're all right. It offered some benefits to certain strata of society but as most of our ancestors were serfs and basically slaves it made not a jot of difference.

Like the second amendment, it was written in a different time and for a different reason and it's invoked these days to perpetuate whatever view you subscribe too; in the US that's you can't be man without a gun to kill people with, in the UK the fact fuck all has changed for us ordinary folk in the last 1000 years.
