these undesirable people are people who look like me, indonesian of chinese descent. They way they told their murderous stories, they didnt even consider us as humans, not even on par with animals.

Numbers on the purge victims indicate that Indonesian Chinese weren't a main target, but like happened in Malaya what started as "get rid of the Communists", could easily be turned into "And all the Chinese are Commies, right?" - they also often happened to be successful businesspeople, so bonus if you owed them money.
