Um, there isn't much room for debate here. Maybe create more of one, Hot_n_spicy? I mean, at 11 - 13, no one can really argue that it is true love and that they're ready for a relationship. It's just holding hands and stolen pecks in the corridors. Howeverr, when it gets a little older, that's when the debate comes up.
Some people think that dating before 16, or even 18 is wrong. You should concentrate on your studies, and you're not emotionally mature enough to handle a proper relationship. Others thing that it's totally normal to date at 16, or even younger. How else are you going to make all the mistakes and get your heartbroken etc? Others don't even think dating is a good thing! Though I don't know anyone that thinks that "/ But I'm sure there are people out there who think that xD
Before 14, you're too young and naiive. Even at 14 you're still like that, 15 it's a bit better but still pretty damn stupid xD Doesn't mean you shouldn't be dating though, because you get to make mistakes whilst you're still young and you can learn from them.
