Who has the right to Melungeon Ancestry?

The Melungeon List is said to have a couple of Ridge-ites who are keeping people from posting on the list, according to a post on Friday. Many feel that their Melungeon heritage is being denied to them because of the exclusive ridge theorists.

I think the ridge theorists are also supporters of Virginia Demarce's Tri-racial isolates theory. Demarce's theory is that the Melungeons are a mixture of White, Indian and Negro.
