Ditto knows what it's like to be abused and bullied. Many trainers use him only to breed with other Pokemon, and he rarely leaves the Day Care to see his trainer. He only wants to be friends, but he's neglected.
Maybe you don't like someone, but you can at least give them the proper respect. People are not tools to entertain by bullying them or harassing them. People are, well... people. We're all from the same evolution line, but the best part about being human is that we are different in our own ways. That boy down the street is gay, sure. But when you talk to him, you find he likes some of the same things that you do. Such differences such as sexuality, religion, and race don't matter.
Pokemon fans- go out there, and give your Ditto some love! Use it in battle, level it up, take it to the spa, anything but using it for breeding. Pokemon are not tools, they are your friends!
Everyone, just recognize the fact that we are all human. Our similarities and differences should be glorified, not looked down upon in disdain.
