DY,
It is a different story. I never suggested that the CC did not have grandchildren that unfortunately went of the derech.
Unfortunately “ayn bayis asher ayn shom meis”. The draw of the “enlightenment” was very strong.
That is why then, as now, the Rabbonim recommend keeping away from certain hashkofos. And speak very strongly against them.
Further,the story in Nefesh Shimshon is well written.
