OK, there is an upcoming debate on "Calvinism" in October. Over at the fun fundamentalist site, Challies says "this could be a good one". Here is my question. Is this a good use of our time?

Pro - Why this could be good

Every generation does not understand or been exposed to the historical discussions (Pelagius/Augustine, Luther/Erasmus, Whitfield/Wesley, White/Caner???) surrounding election, sovereignty, foreknowledge, etc.
Believers are a bit doctrinally apathetic...well, lets just say ridiculously, sadly, pathetically even, doctrinally apathetic. So this debate shows that doctrine matters.
Some may be encourage at the majesty of God seen in the Bible through a debate like this.
I just love debates...I am convinced this is predestined, I just can't help it.

Con - Why is this good?

Here we have major teachers, professors, evangelists, apologists "going at each other" - don't we have enough deceitful philosophies "out there" to deal with rather than putting all this energy into intramurals?
Could this not just polarize the Calvinist groupies and the Arminian groupies and make a big mess?
Are there not enough people needing compassion and the gospel that need our attention rather than putting our efforts into such an event?

I find myself a bit ambivalent about this event...What do you think? Is this good?
