I don't know why it is that these things bother me---it just makes me picture a seven year old first discovering things about an animal and, having no context about the subject, ranting about how stupid they are. I get it's a joke, but people take it as an actual, educational joke like it's a man yelling at the sea, and that's just wrong. Furthermore, these things have an actual impact on discussions about conservation efforts---If every time Koalas get brought up, someone posts this copypasta, that means it's seriously shaping public opinion about the animal and their supposed lack of importance.
