Every fraternity, sorority, secret society or organization composed in whole or in part of public school pupils, which seeks to organize and perpetuate itself by taking in members from among the pupils enrolled in such school in which they are students, upon the basis of decision of the membership of such organization, rather than from the free choice of any pupils in such school who are otherwise qualified to fill the special aims of such organization, is hereby declared to be an organization inimical to the good of the school system and to the democratic principles and ideals of public education and to the public good.
