Feiichy promoted Dalmatian and Herzegovinian Croatoans as the purest Croatians and descendants of "White Croatians", and for kaykavians she claimed they not related with "White Croatians" at all and they are other Slavs + Celts + Germanics.
Unfortunately for her, Dalmatians and Škutors are closer to general Serbian than to general Croatian average, and from kaykavians they are distant as earth from sky. :)
