In spite of the "wikimedia" name, it's wrong to think of Wikipedia in the same vein as the 24-hour news cycle. It's very good for an encyclopedia to have quality control and remove fringe content. It's meant to be an enduring repository of factual information that some form of widespread authoritative consensus exists on, not a place to hash out hot-topic culture war debates that nobody will remember or care about in 50 years, nor a place for alternative pseudoscience like all the guys who spam physics newsgroups claiming to have disproven special relativity or invented a perpetual motion machine.
Even if those things end up being correct, it's also not a place for original research because nobody who edits Wikipedia is qualified to make the kind of judgment on whether original research meets any meaningful quality standard. Submit to a journal if you think you have a worthwhile revolutionary idea. It'll make it to Wikipedia after it becomes generally accepted and that's fine. I don't think a single knowledge repository can realistically hope to be both a repository of trusted, accepted knowledge of the day and a place to hash out the ongoing debate about what should be accepted knowledge and where we might be wrong.
