Koreh lerabo bishmo is an issur lefi shulhan aruch hilch kvod rabbo.
No connection to smicha, which itself is only a newish institution, only a few hundred years old, whereas the issur of koreh et rabbo bishmo is mentioned in the gemara.
Muflag be hochma bedoro is considered like rabo , hence the issur of koreh et rabo bishmo toward gdolei hador.
berdichever or rogotshever does not classify as kore rabo bishmo .
In the case of Hillel and Shamai the principle of gadol merabban shmo , is used. But this is only valid for someone whose gadlut was so pervasively recognized that it was pashut that gadol merabban shmo. As opposed to RCH’V who, while exceedingly great ,still did not factually fit this specific criteria.
The issur of koreh et rabo bishmo is not made any more lenient because that person happens to belong to a criticized group , to people with your hashkafa
So please acknowledge the truth
one should not say chaim volozhiner, rather say R Chaim volozhiner.
