There are several ways I can think of offhand, but any would change the nature of FR:
I think the biggest problem is that certain factions are unwilling to police their own. Right now, the Bush-bashers, of course, have the highest percentage of distruptors. But, the genuine posters in this group seem so happy to have the support that they are unwilling to out disruptors in their midst.
On the positive side, these things happen in waves. Not too many months ago, one could not help but see antiwar.com or lewrockwell.com articles everytime one was browsing. Now they're impossible to find. Those of us who have been around a while, I think, don't mind it so much because we've seen it before.
I think it helps to know there are people out there intentionally trying to torpedo us. Might cause one to stop and think before being pulled into an agrument.
How pot? How kettle.
There are plenty flying monkeys among the Bush Loyalists, who do little to "police their own."
Seems to me that he's addressing the the non-disruptors here, who can do something about it: think twice, and don't take the bait.
IOW, I see him preaching to the congregation here, not the choir.
It's kind of sad that there are so many emotional buttons around here for the disruptors--the masterflame-debaters--to mash on. We're talking flame bandwidth here, and that's something that, at least in principle, we grownups could do something about.
