Answer:
Because the French were never enslaved, unlike the Haitians.
Step-by-step explanation:
Haiti was a territory enslaved by the French and the Spaniards and for that reason, its constitution is punctual around slavery, since this was a situation that Haitians had to go through. However, France was never enslaved and they do not know the problems that this type of system causes, as the French never suffered enslavement, but on the contrary they caused slavery in other territories, the French did not include an agenda on slaves and slavery in their declaration of human and citizen rights.
