TL;DR: Voat users complain about migrants being hostile, unassimilateable invaders, while acting just like that to Poal. No, x0x7's point is about behavior of Voaters. Typically in right-wing circles, like Voat, people complain about the Bantu Expansion. The Bantu Expansion was when the Bantu people spread out from West Africa to across lots of Africa. Bantu are a family of ethic groups and any African most people in the West have ever seen are some kind of Bantu. The blacks in South Africa are largely descendant from the Bantu that nearly wiped the actually Native Khoi-San people. The Bantu Expansion is pointed to as leftists tend to shriek at white colonizing as genocide while ignoring the genocidal nature of the Bantu Expansion. What x0x7 is saying with this comparison is that original Voat had people much more relaxed and friendly like Poal, but they got driven away by waves of users that were more aggressive and pessimistic, like current Voat users. Voat users tended to be abrasive to newer users to enforce their culture, but try to be on Poal and still be abrasive as they don't respect ours.
