The latest person to film a video for the Openly Secular campaign is John de Lancie, an actor best known as “Q” on Star Trek:

The fact of the matter is that, as somebody who is secular, I will fight for the person who’s religious to be religious. But I would like the people who are religious to fight for me to be secular.
Others who have made these videos include: Rep. Barney Frank, Penn & Teller, Bill Maher, Julia Sweeney, and Arian Foster.
