Psychological/dark = bring in the rape

Okay, so, many authors who write under the umbrella of a genre regarded as darker, more mature or psychological tend to bring in some form of rape, SA, etc. To me, it seems like the genre is used as guise to draw, visualize, and to an extent, satisfy some sort of abuse and rape fetish, cause why do we need a whole ass chapter of depicted SA with all the bodily fluids, panting, blushing, etc.?

Also, and this is my main point, it's *lazy* writing with no creativity whatsoever. What do you mean, the only shit thing that happens in life is rape? What do you mean, dark, twisted and psychological means fucking up some twink and his asshole? There are so many forms of abuse, some very subtle, others have nothing to do with sex or sexuality, or aren't as overt, so why only depict rape? Life throws so many stones at ya, you could depict so many things. But it's always rape. BL is super rapey. It's no different than regular ass porn on porn hub.
