Which other leader would most likely to agree with the problem Sun identified in China?

The correct answer to this open question is the following.

The other leader who would most likely agree with the problem Sun identified in China would be Mao Zedong.

Mao Zedong (1893-1976) was the leader of the Communist Army that defeated the Nationalist Army during the Chinese Civil War. After the victory, Mao instituted the People's Republic of China in 1949, based on Communism. He tried to modernized China and made it compete in the international world, that is why he supported programs such as the "The Great Leap Forward" and the "Cultural Revolution," that mobilized thousands of students in China.

An example of this will be "if the government refuses to provide certain services (i.e., fire and police protection) to churches, that might violate the free exercise clause". If the government provides too many services to churches (perhaps extra security for a church event), it risks violating the establishment clause.
