I’m not saying that anything to do with sexual content is juvenile or even “deviant.” Everybody has their kinks and to each their own, as long as it doesn’t harm others.
I’m saying that nonstop “look it the titties and dicks lololol” is only amusing for a short time and not as a constant stream unless the viewers are hormonal adolescents or are full adults with the mindset and immaturity of adolescents. And rape focused content or killing things with one’s genitals is the kind of thing that directly appeals to people with an unhealthy sexual fixation and a desire to harm others, which is what makes sex offenders. Or incels, who are just as bad for different but often adjacent reasons.
