I want to highly recomend the podcasts from Cool Zone Media
[coolzonemedia.com]
They are secular in nature for the most part and most of the hosts I have heard say they are atheists. Robert Evans for sure Ive heard say that many times. Shereen is exceptional secular from a muslim family. And many others.
Its refreshing to hear secular voices that aren't from Christian background and lots of secular content that isn't about being secular. Not all politics but posting there.
