Goodness, the responses in that Irish Catholic article are weak - and the questions are incredibly selective.. I'm not going through all of them, but just taking the first:
1. I think Stephen’s wrong when he says the moment you banish God, life becomes “simpler, purer, cleaner...”
Firstly, not one of the problems, sufferings, tragedies and disasters that Fry would like to blame on God, goes away. Even worse, as Dmitry Karamazov says, ‘without God… everything is permitted’.
So when Lenin, Stalin, Hitler, Mao, Enver Hoxha and Pol Pot ‘banished God’, they banished millions of human beings too.
It's extraordinarily simplistic and, in fact, simply incorrect to say that every single person involved in "banishing" those millions of human beings had no belief in god. And it does give a bit of a problem with the many, many instances of torture and killing that have happened in the name of a god. It is also ridiculous and extremely offensive to state that, for people who don't believe, everything is permitted. There are millions of atheists who live an entirely moral life because they want to, not because they believe in a being who allegedly tells them to.
Neither Fry nor anyone else claims that evils go away if you don't believe in god. They must know perfectly well that his point is that life at least becomes simpler when you don't have to tie yourself in knots finding some excuse for the supposedly omnipotent, beneficent being who nevertheless allows them to happen.
