Discussion is more fecund when opinions differ. Differing opinions, in addition to raising the quality of discussion, breed dissent, and at times, anger. This anger sometimes spills over into threads, which is regrettable, but it is also inevitable. Flaming happens, but peters out, and then discussion continues. This policy will catch genuinely offending threads, but will also catch legitimate discussion as well. The sole remaining Edit thread, for example, is an area that is often ripe with trolling newbies on both sides of the fence, but we've managed to keep it civil for nearly 2000 posts. Under the new policy, when the next round of newbie trolls come cycling through (there are a few new arrivals now, in fact), it could be locked, or the regulars banned. That would be inherently unjust, and is now plausible with this policy. I am afraid that this policy was enacted before it was thought through and the consequences realized. Besides, basher/gusher conflict is inevitable, and even "official policies" won't stop them. A snowball lasts a long time in Hell if you put a little hat on it.
