What are your favorite "reason" channels on You Tube (or other), and why?
Aron Ra: Foundational Falsehoods of Creationism
He can intone more polysyllabic words per minute --even off the cuff -- than anyone else, and do so with conviction to build a formidable argument. His nickname is "the Texas Tank" and he does tend to roll right over people making poor arguments.
Also, he has way better hair than Edward Cullen.
Seth Andrews: The Thinking Atheist
Afterlife is one of his best, IMHO. The podcasts are a bit of a mixed bag due to being part commentary, part call-in shows. But his videos are thoughtful, well written, and have very high production values.
Truth Surge: Excavating the Empty Tomb is a substantive, well-researched, well-produced series. His music videos are quite nice, too, even the satirical covers.
Wildwood Claire: Her "Coffee with Claire" series features often painful clips from anti-science, anti-reason demagogues, and she doesn't sugar-coat her contempt. Her Geodyssey series is entertaining and informative on an academic subject that has not been 'popularized' for the general public.
