A is for

Any practical and/or theoretical position that tends to support a structure of power based on the anti-values of discrimination and violence.

This is not a doctrinal position and it does not refer to particular situations, or to the commission of specific acts that may well be reprehensible from the perspective of humanist ethics. Rather it is a behavior that in practice appears like an inverted image of the humanist attitude. In concrete terms, the a.-h.a. is a personal emplacement or stance in the world, an “objectifying” mode of relationship characterized by the negation of the intentionality and liberty of other human beings.
