Breh, that's even an issue really. In the continent of Africa you don't just get to be from some where because you're born there. This isn't a new idea.
I mention Africa specifically because you could say it's Africans denying Africans.
Earlier I mentioned that a lot of a atrocities like this happen in many African countries as well.
Additionally, someone mentioned it, but the Bahamas is another Black nation doing the same (as far as citizenship). My ex was Haitian and has Bahamian family. When we went to Bahamas all they were complaining about was their difficulties in getting things done without citizenship
Adriana Martell is right that many of you seem to get REALLY excited when it happens in DR v Haiti.
