You haven't "shown" (i.e. demonstrated proof) of anything except that you don't understand was "factionalism vs racism" means, sorry.
And you haven't even read my post. I protest against the removal of races with extremely different characteristics as a driver for differences. See how it is on earth, with simply ethnicities with no technical differences, we already have very strong cultures derivation and differences. I think it's stupid, in a purely fantasy world where there are huge technical differences between various races/species, to deny that it makes for a much richer and vibrant world when the cultural differences logically derive from these differences (and where these differences can be traced back to myths and legends, which make it even better).
And "factions" is just another silly word thrown in there without reason, because "culturism" doesn't make the cut where as racism can be totally ambiguous, especially when, again as demonstrated, it is certainly used in a much more nasty context by the same poster on exactly the same kind of topic. And when, as you pointed out, when factionalism was used, but no, racialism was rejected out of hand although it's the same kind of construct, instead falling back on the insulting word. This is intentional and degrading.
So no, "factionalism" leads only to humans in funny hats, and actually to just different kind of stereotypes, most of which will end up being taken as offensive anyway. At some point, you need to recognize what is happening for what it is.
