Martin Casas has had an unusual career: he worked in politics for years, starting as a White House intern, then supporting the campaigns of Howard Dean, Hillary Clinton, and most recently St. Louis Mayor Lyda Krewson. But in recent years, he’s opened comic bookstore, Apotheosis Comics and Lounge. Apotheosis is an explicitly social-justice oriented bookstore, a community venue which seeks to use comic book stories to promote social change. James speaks with Martin about how superheroes have inspired and supported social justice movements through the decades.
