The founding fathers of this country declared independence because of unjust taxes, and being forced to quarter British troops, among other reasons. The battle of Lexington and Concord took place because the British were trying to seize weapons.
I believe the colonists had the right to defend themselves. The taxes were unjust (because there is an absolute moral standard for justice), and they were right to fight for justice.
Watch this and tell me this is not much worse than what the colonists were facing in the 1770s.
