When Sagan fell ill, shortly before his death, a wide number of professional astronomers and planetary scientists I know refused, some rather insultingly, to sign a get-well card someone else was passing around at a conference I was at.
Knowing how Velikovsky was treated by astronomers, and Halton Arp was treated by astronomers (they wouldn't let him play with their toys, and refused him telescope time), perhaps this says more about astronomers.
