JC, Mostly it was the representation issue. The British were justified in wanting to recover some of the cost of defending the colonies from the French during Queen Anne's war, (French and Indian war in America) and the Indians generally, but the colonists got no ay in the issue at all. Another issue that was important but gets very little, if any attention was the way England suppressed manufacturing. The colonies of most counties were intended as sources of material and CONSUMERS of finished goods. Not manufacturers who would compete with the mother country.
While it is true that when things got tense the British requested citizens of Boston to turn in their arms and ammunition for storage, the only arms they actually made an effort to seize were those stolen from Ft William and Mary in Portsmouth NH the previous December.
While these stolen arms were the spark that opened hostilities, they had not been an issue.
