Okay, so do you know what feminism is? It's when people believe that girls and boys should have the same opportunities and be treated the same way, no matter what their gender is.
Now, technofeminism is kind of like that, but focused on technology. You know how we use phones and computers and stuff like that? Well, technofeminism says that everyone should be able to use those things, no matter what their gender is, and that those things should be designed with everyone in mind.
See, sometimes technology gets made with just boys in mind, or just girls in mind, and it can leave some people out. But technofeminism says that everyone should be included and have the same opportunities to use technology.
Also, sometimes technology can be used in ways that hurt girls and women, like when people bully them online or use technology to stalk them. Technofeminists also want to make sure that technology is used in a safe and fair way for everyone.
