That is what I meant. Simply do not expect that Dachau is something like Auschwitz. I said "Dachau has not do too much with religion" and it was certainly not a centre of the holocaust such as Auschwitz or Treblinka but founded as a prison camp for political prisoners (as you sadly could and still can find them in other parts of the world too).

At least from what I recollect it was never established as a camp for jewish prisioners. After the Nuremberg laws and "Progromnacht" Jews were imprisioned in Dachau, however, as I understand not because they were Jews but more because they were "used" for political reasons.

And you are certainly right with the difference between concentration camps (to my recollection an originally British and/or US invention) and extermination camps which could be defined as an "industry to kill human beings", a very Nazi German thing.

Dachau is very important for German history as such and to understand Dachau you need to know quite a bit about SA, SS and the competition between these two organisations and 1930 to 1945 German politics and society.
