Yabia, there is still a divide between the baladi, who still keep original rambam-based halacha, and shami community, which adopted shu”a. They get along fine socially; they have a beis hillel/bais shamai dynamic.
We can’t bemekabel things from any group which contravene our mesorah; the fact that they’re an ancient community notwithstanding.
AAQ; please provide a source for…. Everything? The rogotchover was a chabad chosid, he was far from “rationalism” in the context of how maskilim and quasi maskilim attempt to besmirch the heiligeh rambam.
The rogotchover was famous for saying that everything in moreh nevuchim is in chazal, that the rambam didn’t copy from or was influenced by the philosophers that he used to articulate his hashkofos.
