Great start out of the gate from a thoughtfully and thought-provoking team.
A well needed voice of reason about a fundamental human right.
I’ve been subbed to the OSD weekly email for a while now and it’s something I look forward to reading every week. OSD moving into the podcast world is a great move and I look forward to this new form of media.
I have been receiving OSD’s email articles for years. Very well written, sound reasoning and easy to follow. Excited to get more content in podcast form from them.
So excited for this podcast. Finally! Thank you
Thanks for doing this :)
