you have nothing to prove they believe this, and it's worded like someone who's trying too hard. 'actual' otherkin don't typically believe in this, in fact they are pretty aware of how fake it all is, but it is seen as a coping method for them. who knows if it works or not, but if it makes them feel more comfortable i really dont care.
im clicking a couple of these and they're all otherkin stuff, so i assume it all is. see the above, and to be honest? being otherkin is definitely NOT on the same level as this guy. like let's say everyone's taking them completely seriously for a second. one believes they are 'spiritually/mentally' an animal or whatever, and this guy, says he is literally an animal. not to mention he threw in the 'trans-' part, which is likely mocking actual trans people. just like the trans-racial stuff.
