We know that. This is just a meme template that's making a joke about girls in drama movies. Also, sexism is making stereotypes and false claims about someone based off of their gender. This is honestly just a harmless joke making fun of what people typically use time machines for in movies. Like, take it as a joke, this isn't saying explicitly "this is exactly what girls would do if they had a time machine in real life". It's just a joke that's not trying to offend people.
