Why is the Island of Hispaniola shared by Dominican Republic and Haiti It very stupid?

It's not correct to say that it's very stupid for the island of Hispaniola to be shared by the Dominican Republic and Haiti. Haiti and the Dominican Republic are two distinct countries with different histories, cultures, and languages. The island was initially colonized by Spain, but the Dominican Republic gained its independence in 1844, while Haiti gained its independence in 1804. While there have been various conflicts and tensions between the two countries over the years, both nations have their own unique identities and contributions to the global community.
