Well Well Well! 
micah, restrain yourself! 
I contend that without investigation of the tabooed subjects which are barred on this forum, no conclusions will come close to quieting the questions in our debates. We can only scratch the surface of any understanding, but the digging must stop and we go home.
Well, I don't know how else to say it, unless I took a specific post and re-wrote it as an example as to how pretty much ANYTHING can be discussed without using certain hot-button terms that just lead to fights. Many weren't here when all the fighting took place, so to suggest having free reign to just say whatever one wants would somehow fix things, I'll have to disagree. Not everyone is mature enough to handle it. All you have to do is a search on 'free will' or 'all sovereign' in the forum search box, and you'll see what has happened in the past - and that's with the worst stuff having already been deleted!
As far as scratching the surface, again, I believe pretty much anything can be discussed in creative terms. The point is, to not just reach for the "easy option" of tossing around catch-all phrases that in the end, really don't define the subject matter anyway. They're just a name for something that people can still fight about "ok, what does that mean"? For instance, is it free will, limited will, man's will, etc... or sovereignty...does that mean man doesn't make any choices at all, that he's a puppet on a string, a robot with a computer chip that was pre-programmed by God, or more so that man does make choices but within parameters God sets and allows, etc., but the end is ensured by God. See, just using a term such as free will or all sovereign doesn't explain those things - they're just some sort of categorical term that's used, that people still have questions about, and historically end up fighting about. So it doesn't get settled anyway. Again, just read through old threads from around 2007 and 2008, and you can see that it never got settled. People got feelings hurt, left the forum, and have been banned from the forum; all without it still being "settled".
All that said, Gary's main thrust for the forum is The Victorious Gospel of Jesus Christ; not to solve every possible problem known to man. So it
is somewhat limited - really from
anything that might end up distracting from that core message. That's also why it's more of a
discussion forum rather than an open, general
debate forum. So although WAY MUCH more is allowed than just strictly UR discussions, yes, there are some limits - and ensuring those limits is not always easy nor does it have a simple formula.
