[1] Wyneken became a personal advisor to Konrad Haenisch, a German social democratic politician with the Prussian Ministry of Education, during Germany's post-World War I revolutionary period.

Wyneken was involved in two decrees, on school community (Schulgemeinde) and religious education, that were assailed for their democratizing and secularizing effects and quickly repealed.

[2] In 1919, Haenisch helped restore Wyneken to lead the Wickersdorf school, but he was ousted the next year upon a guilty conviction for homosexual contact with students.

Wyneken responded by publishing Eros (1921), which advocated for pederastic relations between teachers and boys said to exist in ancient Greece in defense of his actions and philosophy.

[2] He continued to work as a freelance writer and unsuccessfully attempted to re-enter West Germany's school and youth policy debate.
