There aren't many instances in history where people are actually systematically exterminated on the grounds of their race, so Haiti is of historical significance.
It is indeed quite unusual for a chattel slave uprising to actually succeed. It's more the norm for them to be crushed and for their oppressors to continue to brutalize them with no consequences for decades and centuries to come.
Nobody bats an eye at the reprisals that follow when the slavers win.
In the case of Haiti, the country was isolated internationally for decades as a result of the revolt. The US refused to recognize Haiti for nearly 60 years, ironically despite the fact that the US was itself founded on a revolt on grounds that were less serious. This naturally stunted Haiti's development economically.
If you read the Wikipedia page rather than being inflammatory they extended full citizenship to Polish and German people there who turned against the remands of the slave state, so your assertion that this massacre was based on skin color rather than affiliation is false.
Your race baiting and lying is what should be removed.
“ The massacre excluded surviving Polish Legionnaires, who had defected from the French legion to become allied with the enslaved Africans, as well as the Germans who did not take part of the slave trade. They were instead granted full citizenship under the constitution and classified them as Noir, the new ruling ethnicity.”
If you're going to heap moral outrage on events 220 years ago, apply it to the whole situation, not just the part that makes you uncomfortable. Chattel slavery is utterly unconscionable and irredeemable, as is every society that participates in it.
(It's also weird how you're excluding the part where the Polish and the Germans were enfranchised by the Haitian government.)
Some people might say that "exterminated on the basis of race" isn't inaccurate if French is the race, not "everyone without lots of melanin." If someone killed all African blacks but spared some dark-skinned Indians, that would also still be a genocide.
While we're being complete, let's remember the part that the genocide extended to poor whites (not slaveholders) as well as women and children. The fact that they gave a pass to those who allied with them shows that the perpetrators were strategic, but does not detract from their bloodthirstiness.
As someone who believes in Karma, I am not surprised that a country founded on revenge at the race level has never managed to become a good place in any sense of the word.
