Okay kiddo, let me explain what opposition to pornography means.
Do you know what pictures and videos are? They can be really fun to look at, like pictures of cute animals or funny cartoons. But some pictures and videos aren't good and can make people feel sad or uncomfortable. That's what we're talking about when we say "pornography."
Pornography is pictures, videos or writings that show people in sexual situations. Some people don't think this is a good thing because they believe it can be very harmful. They say it's bad for people's feelings and can cause bad problems. They believe that pornography can hurt relationships between people, make some people feel really bad about themselves or can make people have bad ideas about what sex is.
Opposition to pornography means that some people don't like it and don't want it to be easily available. They might write letters, talk to lawmakers or start a group that tries to stop people from making or sharing porn. They want people to know that pornography can be really bad and can hurt people in many different ways.
Some people disagree with this and say that pornography can be okay and that people can watch or look at it without any problems. It's important to remember that people can have different opinions about things, but what's most important is to be respectful to one another.
