The site is not really geared for defeating adversaries so much as fellowship and sharing around the message of the salvation of all through the glorious gospel of Jesus Christ - as established through the scriptures properly translated.
If we wanted to we could set up an overt debate section where people could slug it out, but that was never the purpose of the owner of the site, nor is it, as far as I know my fellow moderators hearts- desired by us as moderators.
There are other places where a more hardline, conflict of position and interpretation approach is taken, ad they have their function. The function of Tentmaker, as stated in the forum guidelines, is to be a tightly moderated discussion forum based in a scriptural presentation of UR, and as I see it that is mostly done with a pretty fair amount of leeway- usually stopping short only for 1)direct challenging of the scriptures as inspired and 2)Unkind, or overly hostile, or deliberately contentious and condescending attitudes.
It is not our desire to exclude ANYONE, but in order to fulfill our purpose it is necessary to establish certain parameters and guidelines and stick to them.
We don't do that perfectly- but we do take it seriously, discuss situations as they come up before taking action, and try to get a consensus before we do whatever we decide to do, as Jab was saying :o).
