If it isn't on wikpedia, it's tinfoil stuff? Even though anyone can put anything on there?
I bother to explain how this works and this is your understanding if it? Your reading comprehension is as poor as your argumentation techniques.
But seriously: Wikipedia has a lot of tinfoil stuff, too. First of all, it's in the nature of a wiki. Anyone can edit one, which means that there will always be inaccuracies and poorly researched subjects. Wikipedia, specifically, does attempt to address these built-in weaknesses, however. If you're interested, the Help pages do a decent job of explaining how it works.
Second, the tinfoil stuff are valid topics, too. From 9/11 conspiracies to Zionism, the point is always to describe the subject as factually as possible, providing as many sources as possible. Ideally, there should be no bias.
Because you're accusing me of "tinfoil stuff", when you are using a site that you've just said has that kind of stuff on it.
True, there should be no bias, but that's not always the case on there.
Let me try to explain this. Feel free to ask questions if you don't understand.
Wikipedia is basically an online encyclopaedia. It contains articles on just about anything, from the war in Syria to Game of Thrones episode guides and pretty much everything between, including 9/11 conspiracies and ancient aliens. This means that there will be factual articles on the tinfoil stuff, just as there will be factual articles on the IS.
Anyone can add an article or update an existing one. Regular people, the tinfoil crowd, the CIA. Anyone. And anyone can review them.
And there will be sources. Most more controversial articles get a lot of them because they get edited often, and because it's the best way to back up your stuff. An article that lacks them will be flagged as such.
If you're an expert on something, you'll probably check out the topics you're interested in on Wikipedia, to see if they are reasonably complete and correct. It's in your best interests. Take me, for example. I am an acknowledged expert on some topics and so have done just that, because I know that my knowledge will help others, but also because like so many others, I simply think it's very cool that you can look up pretty much anything on the web and get better answers than what a simple Google search will provide.
