Update: OK GUYS SO APPARENTLY I WAS WRONG ABOUT WHAT OTHERKIN MEANS. TURNS OUT I STUMBLED ACROSS SOME SORT OF FETISHY THING THAT GAVE ME THE WRONG IDEA, HENCE THE KNEE JERK REACTION.
So, I'mma copy and paste what someone kindly explained:
"otherkin are people who believe that they were animals in their past lives. some believe that they were an “animal born in a humans” body, but as an otherkin, i don’t really believe that’s true. i have to respect people’s opinions, though, i realise.
we don’t really “identify” as an animal. we have ‘kintypes’, yes, but that’s just to tell people which animal we believed we were in our past lives. for example my kintype is thylacinekin, if that makes sense; i’m sorry if i don’t make any. "
So it's a reincarnation/spiritual thing, not some modernisticismful prgoressive movement.
Let your otherkin speak for you.. ACTUALLY THOGUH I properly know what otherkin is now. Turns out I stumbled upon a, uhm, more progressive type of people that gave me the wrong impression o.O But it's apparently a reincarnation thing. THERE I STARTED A DISCUSSION YOUR TURN :3
