Thats easy. Haitians. They’ve been illegally crossing into the DR for years and and have destroyed many areas like feral animals, so says one of the most good and decent a Christian men I know from the island.
Your point is dead on accurate.
I have a good friend who is from the DR and he HATES Haitians with an intensity that is very off putting. He’s a great guy and a great American but you stand back when he gets on a roll about Haiti
