If you don't want to racemix.. fine... you can't tell your fellow countrymen they can't marry who they want. You have the right to keep your own personal property white, but as a leader you can not demand everyone in your country follows your values, that is fascism.
And many people on that land are non-white.
Yeah... mothers with starving children... truly invaders!
