idist

A speaker or proponent of Ido (a constructed language).

[…]but on the other hand the Idists are not so few as their adversaries generally say, and among them are a good many who before 1907 were leaders and editors of Esperanto in the various countries.

Synonym of intelligent designist.

A major question remains, however, regarding what is to become of USAmerican creationists (many of whom are also now IDists) who have quite obviously fallen behind most of the world when it comes to science, philosophy and theology/worldview collaborative discourse.
