Why is innocence and decency so hated? Especially when adults are innocent and decent?

I've seen how innocence and decency has become a very hated thing. Children and underaged teenagers are expected to grow up too fast and they are also expected to get into very age-inappropriate things, and adults are expected to show off their sexuality in many ways. I am a 23 year old female and I don't want to show off my sexuality at all. Not even in the less revealing way, like wearing some sort of makeup or high heels. I rather associate myself with the innocent girl next door type of girl than a sultry sophisticated enchantress. To be honest, I also still enjoy playing with some children's toys, because they can be very interesting, and I also love those children's experiment kits that come with some items and some types of ingredients, like the laboratory types of kits. I also like cartoons and moe anime (anime about innocent girls living their life), and I enjoy J-pop and Disney pop. When it comes to clothing, I love wearing clothes that are inspired by J-pop idol groups, and I also love colorful 80s and 90s style clothing. And people shame me for this, and people suggest me that I should rather be a sultry sophisticated enchantress type of lady, when I don't want to. And when I tell them that I don't want to be a "thot", they end up getting so angry about it and they accuse me of misogyny, when I actually don't mind it if some other female wants to be a thot. Why is innocence and decency considered so bad nowdays? And why do people want children and underaged teens to grow up too fast? What's wrong with humanity nowdays? I'm scared.
