I agree that the RICO decision was a bad decision (and for that matter the entire RICO law is a bad law), and the position NOW and PP took was short-sighted at best. But to say that "for the last decade, almost all the bad Supreme Court precedents rolling back First Amendment Rights have had either NOW or Planned Parenthood in the plaintiff position..." is going overboard.
Actually, most of the bad 1st amendment decisions of the last decade NOW had nothing to do with. NOW and Planned Parenthood were with the first amendment on the losing side of Rust v. Sullivan (which decided that family planning clinics recieving federal funds may be forbidden from talking about abortion to patients). The New Party case, deciding that states don't infringe on first amendment rights if they forbid a candidate to be on the ballot on more than one party. The famous NEA vs Finley case and the recent Dale vs. Boy Scouts case also come to mind.
