“They both agree once you are out of halacha, you’re done, and not given any authority or the opportunity to have your opinion entertained.”
This is an interesting statement. From a theoretical point of view it may be correct. From an historical point of view, and looking ahead a few generations, it is not, or may not be.
The hasidim for the most part ignored zmanei tefilah, many to the point of halachic absurdity. The Baal Shem Tov didn’t go into the sukkah on Shemini Atzeres for a reason with absolutely zero halachic validity. People get married at the end of the month although the Shulchan Aruch expressly says not to. None of these people were or are “out of halachah, without authority or the opportunity (right, not opportunity) to have their opinion entertained.”
It is too early to tell what will become of the progressive orthodox movement. It is not a given “lehotzi otam me’haklal”. They follow halachah or at least claim that what they do has halachic validity and they bring sources and logic. Time will tell where they are going with this. I think they are not going anywhere near where the yeshivish think they are. I may be wrong, but I may be right.
If anyone needs any more proof, please turn to what the misnagdim said about the hasidim in the late 1700s. I’ll tell you. They said ??”?, ??”?, ??”?. Chas v’shalom to talk this way anymore, but that was the feeling then. So it is very reasonable to wait and see. Argue, discuss, persuade. But don’t judge yet. It’s way too early.
