a bizarre delusion

It's hard to believe. I spoke of human rights violation and massacre by the Taliban in Pakistan and Afghanistan today in class; a guy on a zoom class who seemed to sympathize with Islamic extremists accused me of being a government propagandist. Worse yet, he asked me to stop talking about it. I can't believe this happens in academia. I must be in the wrong place or the person is placed in the wrong place. What a bizarre delusional world!
