AFP Liu Tianyu, a Chinese student studying at Buffalo University in the United States, has always valued independent thought. But he was subjected to a torrent of online abuse including death threats after he posted to the social media platform WeChat in support of Hong Kong, where the ruling Chinese Communist Party (CCP) is waging all-out war on public dissent and political opposition. Buffalo University later put two of the students who harassed Liu on disciplinary probation. Liu spoke to RFA's Mandarin Service about his encounter with online CCP supporters known as the Little Pinks: RFA: So can you tell us what happened?
