I also feel this post doesn't fit this community. Confusion and disagreement about what fits is unfortunate but very natural because it's hard to define exactly what posts on this sub should be.
The owner once described this community as c/hmmm with text, and even though that should exclude this particular post, it still doesn't really seem to fully encapsulate the feeling evoked by the majority of posts here. IMO, ideal posts to this community also invoke nostalgia and utilize surrealism.
My best guess is that this post accrued a substantial number of upvotes before being noticed by the community moderators. Then, because the community responded so well to the post, it was left up despite breaking the normal guidelines.
Are we sure this isn't satire?
