Is anyone stopping any of the genocides around the world? Governments and citizenry are engaged in many attempts to wholly eradicate cultures and minorities. Sometimes fast, like Israel attempting to eradicate Palestinians. Sometimes they are slow, like the barriers put into place against indigenous communities after generations of genocide against them.
It's not new either. Sudan, Uyghers, Rohingya, Yazidi, Armenians, Hutus, Tutsi, Bengalis, Cambodians. The world has stood by and not intervened in many of these. Heck, Palantir just posted that they believe some cultures should be eliminated in the United States.
It's grim out there.
"The world" cares about some more than others. That's why the plight of the Palestinians is daily on the news, while that of the Yazidis or Druze is not.
