I enjoyed reading this however I want to pick you up on one point, the discusion of Truth.
This is pivitol and I understand why the person you mention dwelled on it.
If you look up Absolute Truth you will see that Athiests deny it exists.
Even Wikipedia see's this as being a nonsense.
You see to argue that there is no absolute truth requires an absolute position, in itself therefore an absolute truth.
Thus philosophically there must be an absolute truth but in denying it Atheists allow themselves to focus on Relative truth which shifts like the sand.
We can truly claim that the problems we have with truth in society today is due to Athiesm and the 1933 manifesto. With no absolute truth, we are able to be bouyed up and blessed by 'Post Truth' and 'Fake News'. In my view this is all due to Atheism and its relative truth being dishonestly promoted into society.
