(If you're an atheist) You shouldn't debate theology with religious people. The whole idea of religion is that they 'believe' despite their experiences, facts, reasoning and logic. There's literally nothing to gain from using logic and reasoning to debate religious people.
edit: also the article is sarcastic. You shouldn't retreat into yourself just because you cannot agree on something. Talk about something else.
How can there be nothing to gain, when discussions around the subject helped convince me about atheism? I was born catholic and my family is catholic. If no one talked about it, I'd probably still be going to mass every sunday.
Some religious people believe because of their experiences.
See the (very rare, statistically) experiencers of spontaneous remissions the Catholic Church declares miraculous healings, such as Dafne Gutierrez:

I'm not personally sure that's a supernatural event, but if I'd had my eyes deteriorating for years, undergone multiple failed surgeries to stave off blindness, become fully blind, had doctors tell me I was irrepairably blind, and lived without eyesight for years, then had it come back within two days of praying to a Catholic saint for healing...
Well, I doubt I'd still be agnostic after that.
