Or thoughts on Pinocchio,
I haven't done a good essay a while but I figure I should try to crack one out.
One of my favorite childhood stories is the Velveteen Rabbit. The story of a beloved stuff animal being come "real' through a child unconditional love and companionship as well as fairy magic. It was the perfect story for a little girl like myself that had stuff animals for friends. I had dozens of plush animals and I still have a few around me and I still sleep with at least one. However looking back on the tropes of fiction you see that the Velveteen Rabbit is something of a trope now. It the idea that the love of another person unconditional and unrelenting can fix their problems or a characteristic that other person doesn't really understand or like. A good example is a woman loving a gay man and turning him "straight" or a woman falling in love with a drug addict and getting him clean or an abled woman making disabled man, abled.
For some it's the whole "broken doll" or the "Every girl likes a bad-boy" appeal that makes this trope and it's cousins quite over-used. Now is the Velveteen Rabbit trope generally bad? No it's a trope. A writing tool and a common plot device. It's how you write it that makes it cringe worthy. With Autistic characters, you run into this a lot and characters mostly fall into two tropes. The Organic Android and the Three Legged Dog. Now the Organic Android (OA) is the trope where the autistic character is interesting invoking and somehow relatable, but you can tell he is just a shallow image of a normal person and it almost casts you into the Uncanny Valley. The Three Legged Dog is where the autistic person doesn't see anything wrong with himself, he is happy out going but everyone feels so bad for him yet inspired by his feeling of optimism that is portrayed as sweetness and "aww what a precious and special person". One invokes fetishism the other pity. While Tikaani might fall into the TTLD trope a few times. I see a lot of writers lean on the OA for some reason. It guess it's the attempt to make him relatable but only to make him look like something on a National Geographic documentary. TTLD is common too for compassion but it echoes more pity and voyeurism than compassion.
When writing disabled or anything that is "Other" you must be mindful of the tropes and stereotypes you are using. Tropes are not bad but executing them wrong is.
