Sexual irrelevantists have no 'sibs' but only 'sisters' and/or 'brothers'. Even when the gender of the body of a person who has the same parent(s) has no bearing on the subject of the conversation whatsoever, they will still speak of "their sisters" and of "their brothers". Fortunately, the present language --unlike the traditional variants of many other languages-- does have a word for somebody or someone who has the same parent(s), namely the word sib. Etymologically this term is akin to suus meaning nothing else than one's own. (It is only a coincidence that sib starts with the si of sister and ends with the b of brother.) An awkward way of defining sib is brother or sister (considered) irrespective of sex. In such a definition the language user is supposed to take a sib's gender into account without taking it into account. But purely truth-conditionally it must be admitted that a sib is a brother or sister, and that sibs are a brother or brothers and or or a sister or sisters.

Elsewhere sib and sibling may be treated as synonyms, but we shall reserve the latter term for persons who are members of the same group, particularly for persons who have the same ideals. The equivalents in sexualist subcultures are brother for male sibling and sister for female sibling. Exclusivist trade unions, professional organizations and religious orders are favorite places of such brothers and sisters: "We must fight for our rights, brothers!" and "Beloved brethren, we are gathered together to pray for our sisters who have taken a vow of silence". Both outlaws and legal specialists have formed brotherhoods in the past, and the old law of the land may thus force even antisexualist persons and groups to use the services of such a brotherhood. In 'titles', or when used as a form of address, brother and sister are capitalized as in Lord Exequall used to be Brother Wye or in If she gets her way, Sister Exex will revolutionize the whole ward.

Sibs have a biologic relationship with each other, but no such relationship is required for siblings, altho their emotional ties may be as strong as, or stronger than, those of sibs who grew up together. Neither biologic-materialist nor maritally exclusivistic considerations play a role in our common adherence to the Ananorm or in the establishment of a neutral-inclusive society. Gender is, likewise, not relevant either in this respect. We may be male or female when our interest is an erotic one, or when we want to beget or bear a child, in general we are people with neutral-inclusivistic convictions. Hence, unless the context is erotic or related to procreation, we and our sibling adherents shall not call each other "brother" or "sister". For our ideal is a 'sibling culture' that truly and relevantly transcends all sister- and all brotherhood.
