I have been in south over 10 years, have not heard anybody assault Lincoln.
Can you publish a paper to abuse Lincoln in USA?
Some Chinese assault Mao, because he did not allow government officers to steal the properties of the country, didn't allow them to take advantages over Chinese people.
Who assaulted Mao most in China in the past 30 years? Wen JB. He encouraged YOU YOU MEN to write papers to abuse Mao. Look at what he and his family did when he was in power, they stole over 2.7billion dollars to 2008. Nobody knows how much they had stolen till 2013 when he stepped down his position.
Mao ze dong -- the protector of the benefit of Chinese people
Wen JB -- the biggest thief of all the primary minister in China history
Now, it is clear why Mao has been abused so much. It is always related to the benefit of Chinese ordinary people. What thieves want most is to remove the guard of people, so that they can steal safely.
