I have always wondered if that wasn't possibly the meaning of they/them.

An alternative might be the theory that pedo use the pronouns on twitter to specify what type of child they prefer to harm.

Or is it ever used by victims of SRA who have multiple 'alters'?

Consider a rock. It is genderless. Its pronouns are IT or THEY (for a collection of rocks). But rocks aren't wicked.

Because they are rocks.

Rocks don't try to change from non-gendered to gendered. Rocks don't call you a transphobe if you misgender. Rocks don't try to use the womens' bathroom, compete in female sports, don't shoot up schools, or perform in drag for elementary school children.

Because they're rocks.

Be the rock.

They/them. In my day we called this schizophrenia.
