Ask them for one and then agree to terms, like, they can set the security settings, and have full access to your logs. If you are open about what you do on the laptop, they might agree, if you're going to be dishonest, don't bother, they'll just take it away. Also, you can have a rule that says the laptop is only allowed in common areas, like the living room, kitchen, dining room, office, and they have to be present when you use it, just for a little while, few months maybe to prove to them that you are responsible.
Make sure that they understand what you want, and ask them what they want. If you want facebook, give them your logon details so they can check up when needed. Same with e-mails and other sites.
I don't think they'll have a problem if they can monitor what you do. Also, don't take it personally if your parents check up, you are their child, and they have to protect you. Just act grown up and responsible.
Be open. Communication and honesty is your best bet.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
