Sam, the OU statement gives the impression of “eilu v’eilu”, l’havdil.
This is not about what “we believe”, and our “beliefs” don’t/can’t merely “stake a claim in the national discourse”.
This is blatantly against rotzon Hashem, no two ways about it.
Even the Agudah’s “we do not seek to impose our religious principles on others” is weak. In fact, we wish we could, but alas, it’s technically true that we don’t, because we can’t.
