We have wars going on all over wikipedia due to different views and beliefs that far outweigh the business and pr companies.
Many non paid editors have very in-depth political viewpoints, and they attack other groups reporting on information in articles they disagree with.
The worst I've seen are the feminists against male rape statistics and anything male related. I can only assume its because colleges promote such a militant viewpoint on feminism it runs over into other areas of sexual statistics and thus becomes political.
I've seen many editors who are members of originations who delete anything that could be considered a counter argument with the established, but can often be incorrect due to education and their circle of influence related to their school or organization.
Another example. An amateur historian who would find common misconceptions and provide articles to show the common viewpoint is not correct by using government links. Many editors that are enrolled in college history courses would remove his work. He finally just used his personal page and put up the corrections so at least they are online. The point was he was correction known flaws taught in higher education with GOVERNMENT backed evidence.
It sickens me, that the truth can be deleted by editors with agendas. I've seen the history re-written due to lack of publications of news and tv reportings that are from the early 80's and older. But we can have entire animated tv show episodes articles with great detail, as thats the level of knowledge as historically important.
This is why we need all magazines and newspapers online also, the history and reporting of opnion is harder to argue when the only source is wikipedia.
