Radical Maoist professor Han Deqiang has become the face of Diaoyu Islands extremists after he slapped an 80-year-old man at a protest in September. At a protest against Japan’s plan to nationalize the Diaoyu/Senkaku Islands, an elderly man took offense with some of the protesters’ pro-Mao slogans, and Han, a professor at Beijing Aeronautical Institute, slapped him on the face twice and accused him of being an anti-Chinese traitor.
