Thanks for expanding this into a post - I think your analysis is pretty spot on. The only complicating factors I can think of are the changing connotations of "revolution" (for example, the "Glorious Revolution" you mentioned, which was just subbing in a new monarch the parliament and other elites found more congenial) and the role of hindsight/myth-making, with us Americans from a pretty early time looking back projecting a certain amount of "revolutionariness" onto the event for a variety of cultural and political reasons. As you say, less may have changed than we have long been wont to claim, but the feeling that it was such a tremendous upending of past ways was almost certainly important to what our national character became.

Cheers,
Jeff
