Not even remotely. Mitra insists that black holes are impossible. Then Hawking changes his opinion on a very subtle theoretical issue regarding black holes--a change which, I might add, had been urged on him for years by Kip Thorne, who by any standard is a mainstream physicist--and Mitra claims vindication? Preposterous.
Well, I'm sure that must depend on what the meaning of "black hole" is. But in any case, I don't find "religious warfare" to be conducive to the practice of science --even when one "odd ball" is ganged upon by those who adhere to oft adjusted "conventional wisdom."
