>>48561062AB/DL probably have something to do with a desire for someone to not have responsibilities anymore, desiring to be taken care of, or just fascination with human waste that I can't bring myself to understand other than assuming its masochism. Stereotypically, ABDLs tend to be either really geeky programmers, degenerate furries, depraved pedophiles, overworked individuals, or any-to-all of the above.
On DeviantArt, many fetishes can be traced to cartoons. I already explained at how "Damsel in Distress" can lead to someone having a bondage fetish. Cartoon slapstick can morph into inflation fetishes. Kaa from the Jungle Book is featured in some DeviantArt crap directly, and there's plenty of snake coiling and hypnosis stuff there without him.
The question of how one gets a fetish is the one many of us wish to know about.
Do people choose the fetish?
Or does the fetish choose them?
Arguments to the former would say what people watch and read will influence what they like. Sit your kid in front of the Jungle Book and there is a good chance they'll find hypnosis and snakes hot after puberty smashes them. There's also a lot of men who lose themselves to troonery by consuming sissy-hypno, though I would argue those men wouldn't be trooning out if Alphabet Soup People didn't try to affirm a mere fetish as a complex psychological condition.
Arguments to the latter would argue that fetishes are the human Id expressing itsself through sexuality. Those who want to dominate have a small or large part of themselves who wish to control something. Ever wonder why so many feminist women confide about the joy they experience from getting roughed up by dominant dudes? (Alternatively it could just be political lesbians lying to themselves about their homosexuality because they hate men.)
Of course, all of this could just be one simple culprit:
