In 1775 the English parliament began a war on the various colonies. They lost that war. In the aftermath of that war, they reformed their system of representation and colonial administration.
I recommend you read the D of I for why that revolution was justified.
Untrue. In 1775 the Crown sought to put down an illegal and violent insurrection on the part of their own subjects and it seems to me you'd have supported them as a Loyalist had you been around back then.
What we call our 'Revolution' most British historians properly consider a civil war, or a violent insurrection. It was totally illegal under British law yet it happened anyway.
You sir, are on the wrong side of this argument and on the wrong side of history.
