I don't expect a non-religious society will be a utopia. But the failures of a non-religious society will be easier to deal with when no one can puff themselves up and say "God told me thus ..." Or, if some fool did make such a claim, the rest of society would guffaw, snicker, shake their heads, make sure the fool got the mental health help needed so that no one is hurt, and then goes about their business.
The post was talking about arguments, not force. I am not an advocate of violence; at the moment that is a religious issue. Violence would be one of the issues faced by a non-religious society. After all, we are a species of tribal apes and violence is written into our DNA. Overcoming that will take an enormous effort, and may not be possible. But it would be a sight easier if we couldn't claim that the god of OUR tribe is the REAL god.
