The sons of liberty were an underground resistance organization, that was made up of men and women (known as the daughters of liberty) from the New England colonies that protested the acts that the British government put on them. Some out front members of the organization were Paul revere and Samuel Adams. Most of the members came from middle to upper class families, so they had money. They relied on public demonstrations to get support on their positions against the British government. Mostly nonviolent acts, such as boycotts on taxed goods. However they were not above using violence
The Sons of liberty sparked a nation into rebelling and overthrowing the government. Americans who felt oppressed by Britain cheered them on, while Loyalists to the crown didn't. In reality, they could be considered terrorists and were actually seen as such by Britain and other countries. This is because they led anarchism.
The Sons of Liberty were great citizens of America, because they stood up and fought for what they wanted America to be, which was free. On the other hand, if you get technical about it, they were supposed to be citizens (or loyal) to England, so in that case, no they were not the best citizens of England. Fortunately for the Americans, the sons of liberty were there to support them.
To conclude, The Sons of Liberty broke laws and did bad deeds but are considered by me as well as many to be good citizens. This is because they were on the American side and fought for what they wanted America to be free.
