The News Junkie referred to academic blackballing this morning. Here's an excellent example of the academic McCarthyism that goes on today, from the NYT. (I hate to use the term "McCarthyism" because, although he was a crank, I am not convinced that Joe McCarthy was all that far off.)
It's about Dr. J. Michael Bailey, a sex and gender researcher. Scientific debate is fine, but you are not supposed to use live ammo. When scientists begin using live ammo they have abandoned persuasion, so it makes you rightly doubt their confidence in their positions.
By the way, we wrote about the Transgender thing here and here. At this point, I believe that there is more politics than science in the whole subject.
