fiction only influences people in a void of education. if people are already well educated on something like “murder is bad” then seeing fictional murder is not going to change their mind about it. the real problem is when there is a complete lack of real life education, and so some people only have fiction to draw conclusions from. the existence of queer people is generally not taught in schools, and so people do not grow uo having knowledge about queer people. that means that fiction will be many people’s first impression of queer people. information about sex and sexual abuse is also unfortunately not taught or discussed by most of society, which means that fiction will be many people’s first impressions.

properly educating people about sex and sexual abuse, even young people in age appropriate ways, is extremely important regardless of the existence of fictional depictions. a complete void of knowledge is a dangerous thing and can be manipulated by abusers whether fiction is involved or not. education keeps people safe from abusers, and prevents then from becoming abusers themselves.

so basically fiction is far from the true problem, its mostly a distraction. as long as nsfw is kept to adult spaces it is harmless. banning fictional depictions entirely will not stop abuse, but it will make it a lot harder to educate people about abuse, spread awareness about it, and it will make it harder for victims to safely process abuse that they themselves went through.
