As I already said, natives are not gone, they are just silenced and deprived of their rights. What is your alternative? A settler socialism where we continue to rule only we are internally more equal? In that case you may as well be an imperialist socdem. The “magic coalition” is possible. If you read the BAR articles about “black rage” you will understand the revolutionary potential of Black USians. Fanon shows us the most oppressed are the most willing to fight. The most oppressed here are Black people, colonized peoples, and immigrants. There will be settler allies, people know capitalism and settler colonialism is messed up, especially poor white people which are greater in number than most assume. I myself am a settler ally, willing to fight for decolonization.
