This story at the link below shows how Wikipedia gets sanitized to remove politically incorrect material. Actually, I've edited some articles there and it's not at all difficult to do that. The big trick is to use primary sources whenever possible. They like material like official documents and hard data the best, then open source material like MSM articles, then news aggregators like Drudge or ZeroHedge (where they basically copypasta info from some other outlet's story), and then conservative outlets the least (like Breitbart or somebody's blog).
Anons should try and get some Wikipedia editing done to counteract liberals like the guy in the story below. Again, the strength of your documentation is paramount. John Solomon dropped a huge load of material onto scribd, and that's what Wikipedia prefers (see https://www.scribd.com/user/259237201/JohnSolomon ). Note that someone else can come along the next day and change your recent edit, but you can change it right back.
