Wiki is not a valid source of information and it's obvious why that is. Anything potentially controversial, political, or of a subject matter that can be used as a vehicle for disinformation should be avoided. For information on things insignificant to such matters, it's probably fine. For example, you could probably trust that a wiki about Wilt Chamberlain will be fairly accurate, but a wiki about Alex Jones of infowars will not be. A wiki about fire ants could be trusted, but a wiki about firearms not so much.
And, lo and behold, I just pulled this quote from the Alex Jones wiki: "His website, Infowars.com, is a conspiracy theories and fake news website."
If you watch or listen to his show on a regular basis, you know that it's very much NOT fake news. In fact, it's so real and disruptive to the fake narratives of the MSM that that is why they want to shut infowars down so bad - because it's exposing truth in the face of lies. If it was really fake news they wouldn't care so much about it now would they?
