Can we stop making fun of people who are really interested in certain topics (Dream SMP, Minecraft, Lore, etc...) it can be genuinely harmful. Being "obsessed" with a topic is not a bad thing whatsoever. The only time "obsession" is bad, is when you're hurting another person and/or yourself for it. Plus, when you consider the fact that neurodivirgent people usually have hyperfixations, it puts a whole new spin on it.
TLDR; Stop making fun of neurodivirgent people for having hyperfixations, stop making fun of neurotypicals for being interested in things. You're not funny, you're just discouraging people who enjoy things.
