Apparently the FCC policy of investigating every complaint of on-air obscenity has never changed despite its abuse by organized (and sometimes disorganized) complaint mills. Periodically there arise organized complaint filing groups, often religiously based, who file various complaints with the FCC en masse.

These days most broadcasters have recordings of every minute of their broadcasts. Such complaints are usually quickly resolved by review of the specific broadcast time complained of. The form letters go out to the complainants if the FCC chooses, and the matter becomes yet another bogus complaint in a long history of organized bogus complaints from loosely organized nuts.

At least one long repeated FCC complaint has developed a life of its own. The ongoing and infamous complaint campaign about FCC rulemaking proposal RM-2493 has generated more than 30 million complaint letters in its forty year life, and is still generating hundreds per year. The FCC has been trying to lay it to rest since it began.

Lest there be any ambiguity, the blasphemy law the New Zealand lawmakers announced they would take steps to repeal was a New Zealand law. Why there should be anything wrong with making an overseas controversy the occasion to notice and correct an obsolete yet dangerous part of one’s own laws, why correcting such an obsolete yet dangerous part of one’s own national laws would count as faux heroics, why anyone in Ireland should mind, and what any of this has to do with virtue signaling is beyond me.
