I'm not sure what you're trying to say when you keep calling dark fic writers weird and whatnot, even when they tag their content with warnings. yeah sure, sweethearticism should've never interacted with certain blogs, while having a secret, dark fic blog; it's inconsiderate, disrespectful and selfish. but mind you, you post content with some pretty toxic themes yourself. sure, it might not be as "bad" as incest, but this isn't a competition; and ppl understand you probably don't condone emotionally or mentally abusing someone because they "stood beneath you in the social hierarchy" (your words, not mine). it's hypocritical to label your "brand" of toxic and dark themes as okay, while essentially looking down your nose at people that wish to express other, fucked up themes. it's perfectly fine to have boundaries. you don't need to be okay with incest or noncon. the point is: are you condoning or endorsing bullying people? probably not. the same can be said for the rest of those dark fic writers.
I don’t care whether you personally believe rape/incest is wrong. I’m not claiming I can read your mind. I’m criticizing the way those things are represented and eroticized in fiction. A content warning tells me what is in the work; it doesn’t determine whether the work is harmful, romanticizing, fetishizing, or otherwise worth criticizing. And my willingness to write other toxic fictional dynamics doesn’t mean I have to accept every possible form of sexual violence or taboo as equally acceptable. Fictional harmful behaviors aren’t interchangeable simply because they’re all ‘toxic.’ I can have boundaries, and I can criticize media I think crosses those boundaries. You don’t have to personally endorse something for your portrayal of it to still romanticize, normalize, fetishize, or reproduce harmful ideas about it.
