I understand author is concerned about religious people hurted feelings, but just to be clear: is the point, here, that we shouldn't rectify obviously wrong people because we are sometime obviously wrong ourselves ? Sounds like a chewbacca defense to me.
I think he's trying to provide a reference point. "Here's a way that you may behave that is similar to the way you bemoan others behaving." It's my believe that reference points help further useful discussion, so I think this is a good thing.
I totally subscribe to this vision. I just would have read it more clearly in the article, that's kind of ambiguous, like : "1°) religious people are hurted when you argue with them, 2°) here is what you would feel in their place".
Conclusion could be as well "stop arguing with religious people, you're wrong too" as "don't push their feeling too hard and have some compassion when explaining your arguments" :)
