How did Patrick Henry back up his claim about American colonists that had the same privileges that Britain had?

Patrick Henry backed up his claim about American colonists deserving the same privileges as Britain by emphasizing the principles of natural rights and self-governance. In his famous "Give me liberty or give me death" speech, he argued that the colonists were entitled to the same rights as Englishmen, including representation and freedom from oppressive taxation. He invoked the idea that all men are created equal and should not be subjected to tyranny, asserting that the colonists had the right to resist British rule and fight for their freedoms. This resonated deeply with his audience, galvanizing support for the revolutionary cause.
