Cassandra Xia's bio: "Cassandra Xia (@CassandraXia) is the daughter of Chinese scientists who emigrated to the United States. Her parents raised her on a blend of logic, reason, and immigrant can-do attitude. She emerged as a strategic liberal that strongly believes in free speech and compassionate dialogue. She recently left her job as a Google software engineer to work on climate change. Cassandra's work can be found at cassandraxia.com and workonclimate.org."

Hank Racette's bio: "I'm an uneducated fifty-something father of six who divides his time between writing industrial automation software and opining about the precariousness of western civilization and the enemies, mostly unwitting, arrayed against it. I'm fascinated by words, mathematics, evolution, human nature, emergent behavior, and saving the most successful nation and culture in history from the innocent mistakes of smart people with good intentions. I'm a free-speech extremist and, in general, what used to be called a classical liberal. I can be found on Ricochet, where I write as Henry Racette, on Facebook, and reached via email at hank.racette@gmail.com."
