Americans paid less in taxes than the British mainlanders. Actually King George III wasn't really a tyrant, that is just propaganda.
True (re: propaganda). It was easier to get people to direct ire at one person (King George) than Parliament; Parliament definitely caused much of the consternation, though even that’s just an over-emphasized part of the historical reality. British reps in the colonies, limitations on where colonies could sell/buy materials, etc.
Biggest d*ck move by English Parliament: Ben Franklin testifies to Parliament about Stamp Act; Parliament repeals Stamp Act; same day passes Declaratory Act (which gives Parliament legislative power over the colonies).
