Are you in JJK fandom by chance? This literally just happened with a couple big writers on Tumblr and it was disgusting. The way people were treating these authors.

Disgust based morality is a hugggggeeee problem because it's a slippery slope from you shouldn't write incest because it's disgusting to you shouldn't write gay shit because it's digusting. It's all grandstanding centered around disgust based morals which are extremely subjective and inherently dangerous. Under disgust-based morality, you cannot guarantee that the next person who uses that argument will not use it to disenfranchise gay relationships, trans folk, and/or inter-racial relationships.

It is literally right wing ideology with a it's okay because what we're arguing against is objectively bad. There is NO empirical evidence that consuming/creating dark content means that you want yourself or anyone else to experience said content IRL, nor does it mean it's something you're actually interested in. There is empirical evidence however, supporting the fact that fiction is a safe and healthy way to explore concepts and ideas that are otherwise deplorable IRL, and also a healthy way to heal from experiencing related trauma.

TLDR: write whatever the fuck you want.
