Why does mr. lapham disagree with John Hancock about politics in the book Johnny tremain?

In "Johnny Tremain," Mr. Lapham disagrees with John Hancock about politics primarily because Lapham, a traditionalist and a loyalist, values stability and the existing social order, while Hancock, as a leader in the revolutionary movement, advocates for independence and change. Lapham fears the consequences of rebellion and the potential disruption it could bring to his livelihood and community. This clash underscores the broader tension between loyalists and revolutionaries in colonial America.
