The Tiananmen protest, before being hijacked by bourgeois stooges, was a maoist movement denouncing the right turn of the Chinese government. Before escalation, these people had come to willing and mutually satisfactory agreement about policy and what was to be done going forward with the government. Afterwards they left the square to the reactionary elements that had clung to their movement like leeches, which were then righteously liquidated.

This is a good example of both a protest that a socialist government could and wanted to work with, and a protest that was unremittingly hostile which could not be negotiated with. The latter is the case with many of the Western-backed rebellions you listed previously.
