As the instigator of the thread, I can answer the first question.
The thread is in the debate section. It is there because my intention was to narrowly focus on a topic of specific concern of Christian members. I fully expected us to grapple with verses taken from the NT concerning the Great Commission and Pauline advice to believers. None of those would be relevant to anyone who was not a Christian. Additionally, Christians have a shared language a.k.a. "church-speak" and authority, i.e. Scripture. I felt that would make the discussion more productive, since we don't have to waste time backtracking to explain things we take for granted.
