ALPA's history is written by - ALPA. You really need to read it with a grain of salt, or maybe a bucket of salt. ALPA at UAL is currently run by the 570, so add that into the bucket of salt.
As an analogy, if I wrote my own autobiography, I would be the Most Interesting Man in the World, World's Best Lover, Savior of the World, and Slayer of Staller.
