I always found that to be Chuddy, not least because I had a friend at the time who was and is a fairly committed otherkin. It was particularly strange seeing it come from self-proclaimed transhumanist.

Like if you are a transhumanist and don't want people to be able to become elves if they want what are you even for? Varying forms of "Everyone is a toga-wearing elf around crystal spires of tech so advanced it looks like nature" is your entire idelolgy!
