Answer :
Some of the things that the British did that angered the colonist were, declaring acts( ie raising taxes, ie only british products were allowed) which lead the sons of liberty to tell everyone " hey lets boycott all british goods " . Then the sons of Liberty went on planning on raiding British camps and such, which also caused the British to shoot some of them & angered the colonist even more
Some of the things that the British did, which angered the colonists, were not allowing the change of the western borders after the French Indian War, as well as the increase in taxes after the same war due to high costs, and also not allowing colonies to have representatives in parliament. The Sons of Liberty was the secret organization of the colonists who fought for the advancement of the rights of the colonists and was against taxation and the creation of a monopoly by Britain. They probably would advise colonists to boycott British goods and would probably take more radical steps in their fight.
