The official Wikipedia version of history and political conspiracies is extremely conservative and MSM-approved, but that's to be expected considering they're not allowed to do original research and there are a lot of anti-conspiracy, pro-official-party-line editors.

If you want the exact opposite, check out WikiSpooks. It's basically "all the conspiracy theories, all the time." Very interesting takes on #DeepPolitics as long as you use your skepticism. https://wikispooks.com/wiki/Deep_politics
