Why where some citizens where against the stamp act

What? could you reword this

The purpose of the tax was to pay for British military troops stationed in the American colonies after the French and Indian War, but the colonists had never feared a French invasion to begin with, and they contended that they had already paid their share of the war expenses. The Stamp Act was very unpopular among colonists. A majority considered it a violation of their rights as Englishmen to be taxed without their consent-consent that only the colonial legislatures could grant.
