The major differences between the French and American Revolutions included:
1) Most Americans were property owners. People owned their own farms. The farm might be small, and the harvest meager, but it was HIS. Meanwhile, in France, you had a small number of property owners being ousted by a large number of property-less peasants, followed by fights over how the loot was to be re-distributed.
2) Most Americans were armed, and willing to use those arms to maintain order and protect their own property.
It was much worse than that. They even tried to create Utopia during their Reign of Terror. Heck that probably WAS the Reign of Terror.
The primary difference between the American and the French revolutions was that the former based its claims on faith in the One Who made us. The latter did not.
