When analyzing the colonists' response to increased taxation without representation, the population that would most likely react violently would be the more radical factions of the colonists, particularly those who felt strongly about their rights and liberties. This included groups like the Sons of Liberty, who were known for their more aggressive tactics and protests against British rule.
The frustration among poorer and more disenfranchised colonists, who felt the burdens of taxes without having a voice in government, would also likely lead to violent reactions. Events like the Boston Tea Party were examples of such actions, driven by organized groups that sought to challenge British authority through direct, sometimes violent, means.
Overall, while there was widespread discontent among various colonial populations, those most likely to resort to violence were often younger, economically disadvantaged, or part of organized protest groups that viewed physical confrontation as a necessary means to achieve political change.
