No one is stopping black people from creating an ethnostate. Let's forget for a second that they already have one in Lyberia. Black people can literally move to any neighborhood en-mass and everyone literally leaves of their own volition. They can have Mississippi without a single complaint from anyone. The thing is they don't want to BUILD an ethnostate. They want to take wealth by force. They want someone else to build the infrastructure, the homes, the KFCs and the banks. They don't know how any of that works and think they will just eat at the KFC for ever and pay with money that comes out of the bank and use the infrastructure that will last forever and live in mansions. They literally think that is how white people got rich, having everything given to them.
