In February 1761, James Otis, Jr., gave a long oration against writs of assistance (general search warrants used in enforcing the Navigation Acts). John Adams, who was present, later wrote that "the child independence was then and there born, for every man of an immense crowded audience appeared to me to go away as I did, ready to take arms against writs of assistance."
The colonists had plenty to react to. In my own ancestry I found a lot of complaining about being hemmed in by the Proclamation of 1763. They had growing families that needed room to grow and being prohibited from moving west would eventually impoverish them. Things got worse from there.
