“Sorry, not buying the “daas Torah” argument here.”
You don’t have to. You also don’t have to eat food with an OU on the package, go to shuls that are part of the OU, or have anything to do with the OU. That’s your decision. And the OU made a decision to allow HIR to remain part of the organization. No one is forcing you follow their ruling. You don’t have to daven in a place that has ordained women. But if other’s do, then that’s their choice and they have poskim that they’ve discussed this issue with.
