This guy’s reinstatement to the Church has nothing to do with his position on the Holocaust, as wrongheaded as he may be.
His excommunication had nothing to do with his Holocast fantasies, but with his conflicts with certain Church doctrine.
Israeli and Jewish press need to knock off playing politics with something that is (1) theological, and (2) none of their business.
So what? He acted in a way that caused the Church to boot him out. Being allowed back in is a privilege, and the Church can and should require more than a murmurred (and almost certainly insincere) "my bad" on the technical doctrinal issues in question.
By letting him back in, the Church chose to associate themselves with him. One is known by what one chooses to associate oneself with.
