Yes, you can certainly include the Patriots and Loyalists in your answer to the "who was involved" part of your response.
The Patriots were the colonists who opposed the Stamp Act and other British policies, advocating for independence and representation. They actively protested against the Stamp Act and were key players in the resistance movement that emerged in response to British taxation.
On the other hand, the Loyalists were colonists who remained loyal to the British Crown and supported British rule. While they may not have opposed the Stamp Act itself, they were nonetheless part of the larger context of the conflict, presenting a divide among colonists during this period.
Including both groups in your response provides a more nuanced understanding of the dynamics at play during the Stamp Act's implementation and the broader context of colonial opposition to British rule.
