Some notes after some browsing:
- On a positive note, explanations of one's experiences and feelings still happen, so it would be wrong to claim it doesn't happen anymore.
- However, a big number of posts are focused on finding, establishing and discussing labels.
- There are indeed people who "identify as an animal on a physical level", albeit not many. The line of thinking is exactly as I had guessed.
Apparently, the Reddit community largely rejects this concept, but it's fine on Tumblr.
- I recognized some people, which is neat. Cameos are fun.
- The meta is as tiresome as everywhere else.
