Wikipedia:Avoiding POV funnels

Some funnels are more narrow than others, further restricting what is allowed to pass.

Avoid POV funnels: that is, avoid limiting topics as being constrained by a point-of-view funnel which restricts the possible range of related viewpoints into an unacceptably narrow range. Sometimes, there is a need to have multiple articles to avoid a single article from restricting the coverage about notable topics.
