Actually, I simply think there is no reason to engage in this particular debate because it is of no value
But it is of value. Look back a few decades; remember how repressed and "in the closet" atheism was? Most kids were inculcated with religion by default because that's all that really made it into the public square.
Now, through the auspices of high profile objectors like these, and the rising tide of audibility on the networks, tons of kids know that theism is a subject of great controversy, not one that is settled, as the religionists would very much like them to believe.
The huge holes in theistic reasoning are now on the table, and subject to dissection by some of the finest minds out there. Baseless-assumptions-as-axioms are revealed for what they are; the cries of "but you don't know how X happened" are revealed as minefields constructed by the god of the gaps ideas; the idea that it is ok to have questions with no obvious answer is beginning to percolate about the population without inspiring fear. No longer do all citizens feel that they have to profess a theistic viewpoint in order to be socially adequate. Even the false middle ground of agnosticism is eroding, and all of this is not just good, it's great.
No, a debate like this probably won't move a single member of its local audience to the opposite view; but it serves to strengthen the atheist standing and presence in the community and that makes it very valuable indeed. Here, on Reddit, etc., this debate is very much an important topic right now, in the sense that lots and lots of attention is focused that way. All good, my friend, all good.
