Wikipedia is mostly peaceful.

Rogers Cadenhead noted 156 articles proposed for deletion on December 21. By the end of the day, it reached 225 — but that’s out of 877,600 articles. You’re left with 877,375 articles where the editing is much more egalitarian ...Someone once described Wikipedia as the wild west: you hear stories of shootouts and Indian wars but most people are quietly herding cattle and plowing fields in the background.
