You're missing the context of the exchange. We're talking about how to interact with atheists, and specifically the utility of apologetic arguments in providing a compelling case for the existence of God. In this case, Kurt cited the argument from morality as a good example, and claimed...
Now, I'm obviously not saying God doesn't exist, I'm just demonstrating the obvious flaw in Kurt's apologetic argument. And that leads back to my overall point...we shouldn't be sending believers (especially young believers) out into the world with flawed apologetic arguments, because doing so could ultimately cause them to question their faith.
I see .. I have in the past engaged in these discussions, but found they are just a waste of time .. so I pray to God for the atheist instead of reasoning with the atheist ..
