Randomly thinking about how fetish work, the good indie kind at least, often actively works to try and normalize the #fetish within its space, either by creating an imagined world where said fetish is normalized and the majority of people have it, or having a character with the fetish go through embarrassment and/or persecution for having the fetish, so that the intended audience can feel validated and normalized by it.
In a sense, fetish works are a form of positive #representation, which makes the people looking at it feel just a little less isolated in the normal experience of having a fetish. #RepresentationMatters.
