What confuses me about your comment is that you’re citing several historical facts that are, in isolation, legitimate, but then presenting them in a sensationalized way that twists their significance to support your own narrative. Ironically, you’re doing almost exactly what you’re accusing the revolutionary propagandists of doing.
Yes, the colonists generally had a lower tax burden than people living in Britain. Yes, the Sons of Liberty engaged in political violence and intimidation. Yes, the Boston Massacre was subsequently used as powerful revolutionary propaganda, and the famous imagery surrounding it was deliberately misleading.
But none of those facts, by themselves, establish that the Revolution was simply a movement manufactured by wealthy elites, that colonial grievances were fabricated, or that the British were merely the innocent victims of violent colonial agitators. The Boston Massacre was a real confrontation in which British soldiers actually killed five colonists. Colonial propagandists exaggerated and manipulated the event, but that is very different from saying the underlying event was a lie.
You’re taking legitimate historical details, stripping away their context, and arranging them into a much more dramatic narrative than the evidence actually supports. Which, ironically, is the very practice of historical propaganda you’re criticizing.
And that's ultimately where I think your argument falls apart. Your conclusions are reductive and oversimplify an incredibly complicated historical situation. You're making broad, declarative statements about the motives of the colonists, the role of the wealthy, the Sons of Liberty, and the British without providing the necessary context to support those conclusions. Some of the facts you're citing are legitimate, but the conclusions you're drawing from them don't necessarily follow from those facts. Ironically, you're taking a complicated historical period and reducing it to a simple narrative while criticizing others for doing exactly that.
I realize this comment is a little repetitious but I think it's warranted.
