Wikipedia:An uncivil environment is a poor environment

Can an enjoyable game really be played when its players are fighting?

An uncivil environment is a poor environment to work in. It is not conducive to a useful and positive outcome from an already difficult situation. If editors are not staying within the boundaries of civility then they should be warned accordingly, and if they persist, then blocks should be enforced.

If conversations devolve into uncivil rants at each other, how is that helping anyone? Yes, we all believe our side is the right answer and find it difficult to assume good faith of the other parties, but we must force ourselves to as much as possible, and to stay civil. Else we are just a bunch of arguing editors who are doing exactly nothing for improving the site.

Reminding fellow editors of our need for civility is a good thing as it reminds people to stay useful.
