The British tyrants think that the right to possess knives as "part of any national costume" is more important than the right of knives for self-defense, or the right of British citizens to possess knives for daily use (which seems to me to be a requisite aspect of their dignity as human beings) or for their collective value. This just shows how PC informs the worldview of the rulemakers, and demonstrates that they have no respect for the balance-of-power relationship between the government and the people.
