"Okay kiddo, let me tell you a story about European sexuality before and during World War II. You know how boys and girls have different body parts, right? And that they use these body parts for different things like peeing, pooping, and making babies. Well, some people have different feelings about these parts and what they like to do with them. Some people like boys and some people like girls, and some people like both or neither. This is called sexuality.
Before World War II, some European countries were more open about sexuality, and people were allowed to have different relationships with consenting adults. However, other countries had very strict rules about who people could have relationships with, and some people were even punished if they had relationships that were not approved. This caused a lot of problems for some people who just wanted to be with the people they loved.
During World War II, things got even harder for people who had different sexualities. A group of people called Nazis took over Germany and other parts of Europe and they didn't like anyone who was different. They especially didn't like people who were gay or Jewish, and they did terrible things to them. They would arrest them, put them in concentration camps, and even kill them just because of who they loved or their religion.
This was a very sad and scary time for many people, and it took a long time for things to get better. But eventually, people started standing up for their rights and fighting against discrimination. Today, many countries in Europe have laws that protect people of all sexualities, and everyone is allowed to love who they want as long as it's consensual and respectful. And that's the message we should always remember - everyone deserves love and respect, no matter who they are or who they love."
