Why does this happen (read description for more info)?

[Super Mario Bros.]

My parents say I'm too young to have a Facebook account, and they say that having a Facebook is a bad idea even though they have it themselves. Why is this, and what can I do to persuade them to let me sign up at 13 years old?
