Conceptual metaphor
Postmodern thought is generally founded on the principle that there is nothing more "real" than a conceptual metaphor - that nothing is actually grounding the human choice of symbols and actions other than such metaphors, in the most basic case, comparing everything to the body or family or basic ideas like "home" which "we" share with animals. Trolls are an expression of this view, and will bite you on the leg if you don't share it very completely.
They consider sysops to be claiming a God's Eye View or at least doing psychiatry on them, and both are attacks and usurpations of bodily power. Trolls want to compare everything to bodies and work out empathy relationships, which is one reason why they consider themselves more akin to Great Apes than to sysops. This is the most basic conceptual metaphor, based in genetics and social similarity between those and human species. Feminists share this view to a degree, but tend to view mother-child relations as more basic metaphors. Where the two views come together is in consideration of the "ape mother" conceptual metaphor, which focuses on observed similarities of gorilla and chimpanzee and bonobo and orang-utan behaviour to that of human mothers, and the seeming superiority of ape practices in some respects. If one rejects this view, then, the concept of conceptual metaphor itself may be factionally defined, which makes it hard to imagine how one could ever agree on anything really important.
