Final answer:
The colonists resisted the Townshend Acts primarily by boycotting British goods and rallying public opinion against the Acts through writings such as "Letters from a Pennsylvania Farmer" by John Dickinson.
Step-by-step explanation:
One significant way the colonists resisted the Townshend Acts was through a coordinated boycott of British manufactured goods. In response to the taxation of items such as tea, glass, and paper, the Massachusetts legislature sent a petition to the king and urged other colonies to join in the boycott as a form of protest. This collective action represented a unified front against what the colonists viewed as unconstitutional taxation without representation. The boycott affected British merchants economically and showcased the resolve of the colonies to stand against Parliamentary overreach.
Additionally, intellectual resistance came in the form of writings, like the "Letters from a Pennsylvania Farmer" by John Dickinson, which argued against the legality of the Townshend duties and rallied public opinion against them. These efforts, along with demands for redress of grievances, indicated a firm stance against the British government's policies and set in motion the events leading to the Revolutionary War.
