[7] Although the leaders of the "Central Sarekat Islam" based in Batavia were skeptical of the move towards communism, they appointed Semaoen to their board as well as making Darsono propagandist.
He expressed in meetings and articles that he believed that party mainly represented Indo people and that if they came to power they would relegate native Indonesians to a subservient position.
[9] In October 1920 the Semarang wing of the Sarekat Islam, and Darsono in particular, came into conflict with the central group of the organization in Batavia.
[10] In the pages of Sinar Hindia, he accused Sarekat Islam leader Cokroaminoto of embezzling money from the organization.
[1] In that speech he called for closer collaboration between the Dutch and Indonesian communist parties in the interest of reducing racial hatred.
[1] While he was abroad the Dutch authorities in the Indies discussed that he should be treated similarly to Semaoen and not allowed to reenter the colony when he came back from Europe.
[1] In 1923 the Semarang authorities and the Governor General debated whether Darsono and Semaoen should be deported from the Indies, but decided against it for the time being.
[16] The ill-fated 1926 PKI revolt happened while he and Semaoen were out of the country, and even though they tried to negotiate on the Indonesian communists' behalf with the Soviet party, they were increasingly out of touch and unable to be of help from where they were.
At this time many communists fled Germany, but he was unable to escape for a time, and so he left his son Alam Darsono to stay with Bran Bleekrode, a Jewish violinist living in Amsterdam whose cousin Bram Bleekrode was organizing places to stay for communists fleeing Germany.
