When Brooms Attack

Every once in awhile, I come across complaints of bias or other problems on Wikipedia on news sites. Sometimes I dig through the evidence looking for what is claimed, to make sure that things actually happened as they should. Usually, it's a case of people being all-too-human with one or both parties bumping themselves into a corner, often with some policy misundertanding by one or both parties to boot. I often regret that I never seem to hear about these things until some unnecesary-enough stuff happens to get people banned (or someone storms off). It would be a wonderful thing if people would either be cool-tempered enough to be able to resolve things themselves or if they were careful enough to ask for good guidance when they begin to get close to an ugly situation. I wonder how that social problem can be solved..
