</sarcasm> Two of the conservatives on SCOTUS have direct experience of the extreme Democrat partisanship of pseudo-objective journalism. And none of the others are likely to have enjoyed the spectacle of the opposition to the Kavanaugh confirmation. The question, it seems to me, is how SCOTUS could craft a ruling which delegitimates claims of journalistic objectivity and any and every manifestation of government respect for such claims.
Claims of objectivity are inherently self-negating because belief in your own objectivity is the essence of subjectivity. And joining a mutual admiration society which will claim objectivity for you provided you claim objectivity for everyone else in the society is simply a device for indirectly claiming objectivity for yourself.
On the whole, it is easier — much easier — to get federal legislation passed and regulations rewritten than it is to contrive for the Supreme Court to create new constitutional law.
