If viewed as a whole, Wikipedia is one of the truly great web projects and its success cannot be questioned. However, the model by which Wikipedia operates has its limits and for some things it doesn't work. One of the things it cannot do is to make high quality articles on controversial topics.
We definitely have problems in this area. My current thinking, briefly summarized:
1) Be very inclusive. NPOV can only work if everyone gets a fair chance to have their point of view included in an article (even if not the main article).
2) Center discussions around issues rather than people. Conduct systematic peer review in different categories for every article. Highlight unsourced/unattributed claims in the article.
3) Facilitate forking. It should be easy to create and maintain forks of controversial articles written from a specific group's point of views - not necessarily within the Wikimedia framework, but outside of it. Others can then take Wikipedia, Wikinews or Wikibooks entries and develop them according to their respective belief systems.
4) Eliminate edit wars. The most obvious solution seems to be a "Ban to talk page" feature that does not protect the whole page, but only forces the users involved in an edit war to discuss the issue.
5) Faster response when people violate the rules, by randomly selected trusted user committees or something similar. Milder, but quicker punishments. Less talk, more action.
2)-5) require changes to the software. Have patience, they will come. Some related proposals and documents are on Meta, particularly LiquidThreads and Wikiflow.
In the meantime, my advice is to either keep stirring, or to bookmark the last revision of the page which you find acceptable and wait for things to improve.
