Disappointed that no-one new is taking up the gauntlet from Hitchens, Dawkins, or Stephen Fry, its all old stuff on youtube, come on people!
The gauntlet lies in plain sight, my friend. Feel free to pick it up.
Let me add Neil deGrasse Tyson, Lawrence Kraus to your list of one scientist.
I'd also like to add Sam Harris (as an atheist intellectual).
And because you added media personalities Fry and Hitchens in your list, let me add other known atheist/agnostic with (relatively) high media personalities: Bill Maher, Cenk Uygur, Ana Kasparian, David Pakman.
Regardless, I agree with you.
However look into the Philosophy channel. You'll probably find more atheistic conversations in there.
