When the British imposed the Coercive Acts after the Boston Tea Party, colonists were convinced that the British government was trying to destroy their entire way of life.
To prove this, the colonists pointed to the various provisions of these acts. They noted that the acts took away Massachusetts' right to govern itself. They noted that the acts took away their ability to make a living because they closed the Port of Boston. Finally, the looked with suspicion on the Quebec Act, claiming that it favored the interests of Catholic French people over those of Protestant Britons in the colonies.
Because the Coercive Acts did (in colonists' minds) all these things, the colonists felt that these acts were meant to destroy their economy, their political system, and even their culture and religion.
