I understand it's in part because Tumblr is the space for, among other things, people with very little social skills and self-awareness, and I'll never really tell people they can't post their own brand of positivity in their own netspace, but it never stops giving me a hearty chuckle whenever I see those posts where it's like "Oversharing and infodumping on your friends/others is based, actually" or "Posting the most decadently self-indulgent stories with overpowered self-insert OCs is all you need to do" or anything with that general vibe of "annoying/frowned upon thing or behavior is great, actually" with 150k notes all agreeing loudly because, see, I don't want to deal with any of those things without the proper agreement to do so and respect afforded a third party, friend or not, and I understand it's the kind of thing where it's reinforcement of the shunned and all that, but sometimes, just sometimes, you understand why they are shunned in the first place, and that's less about Quirks(tm) and more about unapologetically deciding to circumvent self-awareness.
