Just say "black people," Vance. You obviously just mean black people but you don't think you can get away with that, so you say "Haitian immigrants" as if that wasn't a dog whistle so loud that a partially-deaf person could hear it.
And it's not like you can tell whether or not someone is a Haitian just by looking at them. All you know is they're black. This is just racism, plain and simple.
