In 1776 the people of America were not oppressed. There was no evidence to suggest that the British were taking away firearms, ransacking homes, and destroying American liberties. They were taxed without representation. The colonists revolted because they feared what the British might do. They were paranoid. They distrusted big government.
I've heard the contrary about an attempt at disarming colonists. Northeastern area i believe. Could be hearsay though.
