The American court system is typically considered the best systems for identifying the truth that we have. It relies on a prosecution delivering facts, evidence, and other forms of argument to make their case. But equally important is the defense. Defense is so important...that the system appoints one when there isn't one. Why? Because with only one side in a debate...the outcome is a sham. The same holds for concepts.
10 years ago, I posted pretty heavily supporting serious gun control. I was mostly alone in this...me vs. ardent gun supporters. Through Sandy Hook and Zimmerman, I was trolled nonstop with some posters collecting information on me and wanting to meet me in person. The board has thankfully moved closer to the position I hold. So I don't post nearly as much there...the outcome is still critical, but my value add is less so.
Here, I have no need to offer defense to individuals whose motivations are impossible to discern. But as nobody else is doing it, I will offer defense to faith and because I know it, Christianity. Just as in defense anywhere else, that will include the positive side of Christianity and it must include comparatives with alternatives. After all, every point of view deserves a second side.
