So I can see that he is interested in and possibly a fan of Lyndon LaRouche, who was a bit of a wackjob but also a free thinker. And he questions whether the treatment of Uyghurs is actually a genocide, which I dont agree with, but is within the realm of rational inquiry. There are no unbiased sources regarding that issue, its all propaganda from both sides. And I can also see that he refused to apologize to the mods of r/socialism.
At no point did you provide evidence that someone was advocating for genocide.
