We shall only discuss one form of partial physical subanthropic exclusivism here which does not relate to questions of sexuality, discharge of bodily waste matter and nudity, namely physical laterality-based exclusivism (X.289). The object of this exism is the habitual use of only one or both sides of the body. (Not only is it 'partial' because a 'side' is merely a 'part' of the body, but also because it always concerns certain parts of the body like somebody's hands.) Altho physical laterality certainly does not only concern the habitual use of one's hands, we shall confine our attention here to this integral manifestation. But also hands can be used in different ways for different activities, and we shall also confine handedness-based exclusivism (X.578) to writing-related handedness-based exclusivism (X.1157). (Altho 'natural' sociobiologists may object that our hands were never supposed or intended to be used to write with, this is irrelevant.)

Writing-related handedness-based exclusivism is exism re the habitual use of only one or both hands when writing or drawing. The lateral manifestations of this unitary irrelevantism can serve as good examples for other unitary manifestations, both physical laterality-based and other ones. These manifestations are (with their binary-decimal numbers):

• unilateral (12): single-handedness-related (exism re the habitual use of only one hand, as opposed to ambidexterity);
• bilateral (13): double-handedness- or ambidexterity-centered (exism re the habitual use of both hands);
• supercomplemental (24): single-handedness-centered (exism re the single-handedness of human or humanlike beings, whether left-or right-handed);
• complemental (25): complemental (single-)handedness-based (exism re the left- or right-handedness of human or anthropomorphically conceived beings);
• first complemental (50): left-handedness-centered or manual sinistral (exism re the habitual or much easier use of the left hand); and
• second complemental (51): right-handedness-centered or manual dextral (exism re the habitual or much easier use of the right hand).

Componential manifestations of (writing-related) handedness-based exism are:

1. abnegational exism re ambidextrous people or manual ambidexterity;
2. aggrandizemental exism re right-handed people or manual dexterity; and
3. abnegational exism re left-handed people or the use of the left hand.
