Good news: she's not one of ours.
Kirstie Alley may not be Tom Cruise, but she is a well-known performer (Cheers and Fat Actress) and a well-known follower of mediocre science fiction writer L. Ron Hubbard's mediocre effort at creating a new religion, the perversely named Scientology.
Glenn Thrush at Politico reprints a series of tweets that Alley has sent out, which claim that the bill in question would require mothers to accept psychoactive medications, and give them to their children, if a doctor prescribed them. This appears to be false. It also includes some loony stuff about "squirting Prozac into the eyes of newborns." This appears to be nuts.
The real issue, obviously, is that Scientology does not accept the use of psychiatric medications. This is their right, we suppose, just as Christian Science doesn't care for medication at all, nor Jehovah's Witnessism for blood transfusions. (Insert crack about Roman Catholicism/"Evangelicalism"and abortion/stem cells/cloning here). Unlike the Christian Science or Jehovah people, Scientology has a well-worked out strategy of using prominent entertainers to publicize its preferences.
Their legal right, yes indeed. But isn't there some legal device for holding people accountable for outright lies? Like, say, laws about libel?
