Is the membership in the German Physical Society acceptable?

My German friend Jonas is asking the question, because the GPS wrote such a deeply mistaken expert opinion on the correct teaching. Among the statements of the GPS are

1.  temperature and entropy are not the foundations of thermodynamics
2.  force is not momentum flow
3.  dipoles are not made of two poles
4.  light does not need vacuum for traveling

If you would tell any of this in court, you would go to jail. What a sad story.
