It would behoove everyone involved in this argument to begin to get out of their heads that there are "their" rabbis and "our" rabbis.
There are only rabbis.
Recently, too much has been attached to one rabbi or another's political, ideological or ethnic affiliation and identity.
This is a terrible development.
The only thing we must look at is the man's scholarship and integrity.
Dividing rabbis in accordance with any other criteria goes against the spirit, if not the letter, of the Halacha.
