It pains me to quote Mr Wales, but this is actually quite clear:

 From Jimbo Wales, paraphrased from this post from September 2003 on the mailing list:
 If a viewpoint is in the majority, then it should be easy to substantiate it with reference to commonly accepted reference texts;
 If a viewpoint is held by a significant minority, then it should be easy to name prominent adherents;
 If a viewpoint is held by an extremely small (or vastly limited) minority, it does not belong in Wikipedia regardless of whether it is true or not and regardless of whether you can prove it or not, except perhaps in some ancillary article.

Keep in mind that in determining proper weight we consider a viewpoint's prevalence in reliable sources, not its prevalence among Wikipedia editors.

If you are able to prove something that few or none currently believe, Wikipedia is not the place to premiere such a proof.  Once a proof has been presented and discussed elsewhere, however, it may be referenced. See: Wikipedia:No original research and Wikipedia:Verifiability.
