Rabbi Gedalia Dov Shwartz and Rav Zalman Nechemia Goldberg are two different people the former lives in chicago and can be argued is MO but the latter is a well respected dayan in Israel and I dont believe is MO.
I actually am sephardi but nevertheless my point is how can you call those who believe in prenup to be conservative. Did all ur big ashkenazi and chassidic rabbanim consider rav ovadia to be conservative because he believed in prenups or heter mechira? they realized that there is a machloket in the matter and accepted Rav Ovadia’s right to have his own opinion so why cant you accept the right for other big rabbanim to have their own opinion too.
The second beit hamikdash was destroyed because everyone held that only their opinion was correct. I hope you change your approach to these different halachik and hashkafic issues and realize that legitimate poskim disagree with you BUT THAT IS OKAY!!!!
