Why does the tax on tea lead to a conflict between the colonists and England? (Chapter 6)

The loyalists refuse to pay a tax on tea. They will try to reach a peaceful settlement, but will resort to violence if the British do not take the tea back to England in twenty days. Sam Adams seems especially eager to fight with the English forces. Because they need boys to help dump the tea into Boston Harbor, Adams initiates Rab as a fighter for the group. About thirty boys will be recruited for each of the three ships. Paul Revere volunteers to lead one of these bands.
