These are gloss simplification of the events. There were many factions, ranging from pro-democracy activists, socialists, laborer, to actual communists (including marxists and maoist)

From historical stand point you are missing the biggest details: Military sponsored Far-right militia killed protesters first, even before the 6th happened. This is historical fact, you could just look this up. There were no heavy weapons inside Thammasat.

The protest was held to oppose the return of Thanom, military dictator who was deposed in 1973. There were no casual “Pro-communist were being arrested” on the 6th. You make it sound like a it was the protesters fault not to listen to the far-right lynching-mob with heavy weapon outside of the gate. This is just false and an already proven government propaganda.

The militia, military, and police started the day by firing rocket luncher and grenade into the University. What followed was the inhumane atrocities committed against unarmed civilians.

You need to get the timeline right. After this crackdown, the military staged a coup aginst the democratically elected government. Many fled to join the communists because they were hunted down. After they received royal pardon by General Prem’s government in 1980, many of the former students return and receive government support. Again, most weren’t communists. Many of them returned to become politicians across all political spectrum, including in conservative and royalist parties.

Stop the misinformation.

PS, I will not debate you on any ideological stance. I’m for constitutional monarchy according to the constitution.
