Do you know anything about ethnickin and whitekin? Are they troll labels? /genq
I haven't heard of those terms specifically, but based on my experiences being in the otherkin Tumblr community during the mid-late 2010s I would bet that they'd be both a) terms used by trolls, and b) terms used by the newly coined (at that time) factkin subcommunity.
I'm just basing this off of my own experiences of course, but factkin itself was honestly like that in the beginning. You'd have a handful of obvious trolls alongside folks who were like "actually yeah this unironically fits me", much to the chagrin of the trolls. A similar term that I had seen floating around that time (I wanna say like 2018?) was agekin, which yes was used by trolls because they thought it was funny, but it was also used earnestly by those of us who would eventually adopt the term transage instead in the 2020s as part of the transID umbrella.
I don't see a lot of those terms used as often nowadays as the usage of transidentities gains traction, but if you're asking because you're considering them for personal usage I'd say go for it! Use whatever terms you feel most comfortable using, trolls be damned.
