Ectonormativity is a subset of amatonormativity, centering around the social concept that every person must have attraction and/or relationships with a person outside of their physical self; the idea that autospec and in-system relationships/attraction are either problematic or not a "real" relationship.
Common examples of ectonormativity include:
-Referring to autospec or in-sys relationships/attraction as "selfcest", implicating that it is comparable to incestophilia, when they are not the same thing [link.]
-Telling autospec people that they are "narcissistic" (also overlapping with saneism towards NPD) and "egotistical".
-Telling autospec people that they "will never be satisfied with themselves."
-Telling autospec people that its "just self-confidence/self-love, not a real orientation, and they're just trying to be special."
-Making fun of autospecs for self-dates, self-marriages, etc, with no external partner to make it appear "normal."
-Making fun of plurals for dates, marriages, etc, where only the shared body is present, with no external partner to make it appear "normal."
-Diminishing the personhood of one or all of the sysmates involved in a relationship, claiming that all the sysmates are a singular being (which is both pluralphobic fakeclaiming and also anti-autospec.)
