I am pleased to hear you say that the 19 letters is a very limited understanding of Hirsch- it is. It was only from reading your posts that I was led into think that perhaps that was as much as you may have read. If you have delved into the more academic writings and understood them, I hold you in high esteem.
Please go back and read what you wrote and what I called you out on. I did not say that Zionism is an ideal of the Hirschian philosophy, I only warned you not to bandy about the term austritt.
If you read what I replied to Ben Turah, you will find agreement in the “light unto the nations” ideal that is fulfilled through living in exile.
