and do I personally know a mamzer?
not knowingly, but certainly in the tshuva seforim there are cases,
including the one I cited above.
Rav Moshe wrote
from memory but I think it is substantially correct:
—-
But to be machshir the first daughter,
there is no place at all to be machshir her,
for she is a mamzeris vadois midoraisa.
He then goes on to explain why the
Rav’s attempts at a heter were meritless.
In fact the very case of the Langer’s proves our point not yours.
for if in fact rav goren permitted them, other rabbanim did not.
this was before rav goren was involved and was not a political vendetta against him.
According to you , it should have been unanimous.
