Final answer:
The passage argues for opposition to taxation on trade and property without representation, reflecting the colonists' principle of no taxation without representation.
Step-by-step explanation:
The main argument presented in this passage is opposition to taxation on trade and property without representation. The query refers to the sentiments that fueled the American colonists' dissent against British parliamentary power to tax the colonies.
It emphasizes the colonial belief in the principle that there should be no taxation without representation. Colonists accepted some taxes for the regulation of trade but objected to taxes intended to raise revenues for British expenses, such as the defense of the colonies, without their consent.
The argument stood on the foundation of charter rights and the long-standing English principles enshrined in Magna Carta and the English Bill of Rights, thereby rejecting direct taxation without direct representation in Parliament.
