Since you brought up Yemen, it's interesting to compare Google image results for the Yemen genocide and the alleged Uyghur genocide. Search the former and you get pictures of destroyed towns, columns of refugees, mass graves, and starving people. But Google "Uyghur genocide" and it's nothing but pictures of protests in Western countries. You would think that the Uyghur people, being much wealthier than the Yemenese and receiving much more attention from Western journalists, would have an easier time getting those pictures out there.
