First Kiss

Hello! I'm asking about the certain tropes found in fiction especially in the bl world such as rape and incest.

I know that there are people who have a preference for it, hell l enjoy a guilty pleasure of incest trope every now and then since its just fiction. But lately I'm starting to feel bad for liking such tropes. I don't condone the tropes when it occurs in real life of course because its terrible period. But I can't help but ask myself if I'm okay with said tropes in fiction does that mean a part of me thinks its okay in real life? A person having a preference for the "rape" trope, does that mean the person's a rapist and support it? Can saying "its just fiction" excuse people in liking other tropes such as shota? And if they like shota, does that mean they're a child predator???

I'm sorry if this sounds like a mess. English is not my first language. I'm sure this question might have already been asked in this site in different ways. I just want to ask your opinions and thoughts about this. I might have just been overthinking though.
