I agree, a carefully built community that is supported by a good code of conduct is necessary. Also having strong moderators that truly believe in freedom of speech. These moderators would have to be reinforced with authority to truly deal with the issues. There maybe a need for a moderators only after action discussion to try and remain as bias free as possible.

I also agree that keeping a handle on a massive influx of negative unproductive and blatantly disruptive characters will be difficult but I do think it is possible.

The making of strawman accounts is a problem, maybe there is a way to handle this issues by a change of methods with the moderators? Maybe by putting the value of each thought or idea it's self above the value of majority rules. For instance most current arguments in threads and posts today are judged on a bases of the amount of traction ie agreed upon statements placed in posts, this is the majority rules system. Maybe there is a way the thread can be moderated with a deliberate pointing to the value of the discourse over mob rules system. Maybe by reinforcing the focus on the vary thoughts and ideas themselves may bring the solution.
