Hardly! While they were not Rightists, in the context of their times, they were almost all substantial property owners, whether from business interests or as landed proprietors. Probably the best way to describe them would be as Libertarians, or "Classic Liberals," with a very considerable divergence, among them, as to just how "Liberal," they were. I believe that most of them considered themselves "Whigs," in terms of British politics of the time.
However, their Revolution was really a counter-revolution, against increased outside meddling in their affairs--following the French & Indian Wars. It was very much a revolt to vindicate property rights, and the right to do business with minimal intrusion by Government. In this is was a natural heir to Magna Carta, so the roots were very Conservative.
The Nazi and Communist Revolutions, on the other hand, while there may have been educated men of property involved, pulling strings, were basically uprisings of the mob in the street--heirs to the French Revolution, also manipulated, of course. The principles of the American Revolution, vindicating the right to be let alone, were the furthest thing from the mob manipulation that the Communists & Nazis employed.
