On Wikipedia, the community expects people to engage with opposing viewpoints — to resolve their disputes through reasoned debate, not through shouting. Im my opinion, their community guidelines have been some of the most comprehensive and well laid out, and strict adherence to them by the community has contributed a lot to what Wikipedia is today!
For instance — right now on the page for Black Lives Matter, there’s an anonymous contributor who is upset that the article doesn’t mention George Soros, who is believed by some on the alt-right to be the movement's ultimate sponsor. (It’s not true.) The contributor accuses the pages editors of conspiring “portray BLM in the most favorable light possible.”“Easy,” one of the editors responds. “Take a breath and let's see what we can agree on.”
