Well it's obvious to me. Fairness of free speech, or the genuine desire to hear diverse opinions doesn't seem to be the reason we non-christians are allowed to post. At least, from my view, that's how it looks.
I feel the supreme reason(s) non-christians are "allowed" to post on this site is:
1.) It brings non-Christians in contact with Christians making an environment where conversions and indoctrinations are possible. Thus "spreading" the word and grace of "God" as so many like to term it.
2.) It gives the "preachy" type of Christian a forum to preach and rant.
3.) It allows for a fellowship of Christain participants to "band" together against a specific issued or "examples of sin" raised in discussion with/by non-believers. Thus seeming to strenthen the "faith".
Honestly. That's why I think I'm allowed on here.
Sure i know there are some very good and fair minded Christian posters that participate and want to hear from all people of all walks of life. But, I don't think that is the Forum's reason for allowing non-christians to post. Otherwise, there would not be a "Christian-only" section. Sheesh, talk about a plain, small scale, example of a religion seeking ultimate domination. Oh well...
