Calling an insurgency a peaceful protest is indeed revisionist if one were to do so.

And calling a revolt an insurgency and calling insurgency where rioters kill over 100 soldiers a peaceful protest with counteraction against such insurgency a massacre is also quite the revisionism.

The timeline of Tianenmen 1989 is

• large continuing peaceful protests for US-controlled school education
• groups of students or "students" killing soldiers on the street
• evacuating peaceful protesters from the square + soldiers killing insurgents still active on the street
• train station incident, unrelated protesters block soldiers with strict orders from entering train
• tanks arrive on square and start patrolling the streets
• Man with shopping bags stops tank on the same street the soldiers and insurgents were killed, then jumps on it, other students drag him off the tank and away.
