Final answer:
John Adams and other colonial leaders opposed the Stamp Act through non-violent means, such as writing articles, creating a propaganda campaign, and drafting official documents outlining their opposition to taxation without representation.
Step-by-step explanation:
Colonial political leaders such as John Adams responded to the Stamp Act by writing articles and pamphlets opposing the act and urging peaceful resistance. They outlined the reasons they believed the Stamp Act was unconstitutional and supported the goals of the Sons and Daughters of Liberty without engaging in their violent actions.
These leaders, including lawyers, printers, and merchants, created a propaganda campaign to educate colonists on the issues and encouraged non-violent protest, while also convening in assemblies such as the Stamp Act Congress to draft formal rebuttals like the Declaration of Rights and Grievances.
