When a parent's mind is made up, statistics aren't going to change it, but if your parents aren't (or can't) pay for your school, what kind of say do they really have on your social and philanthropic extra-curricular activities? You seem to understand college is more than books and classes. And it's great to see you have done your research!

It's hard enough for parents to let their children "go" and send them off to college, and then to do something they (wrongly) assume will be detrimental. All you can do is give them a big hug when you leave, let them know you are trustworthy, have a good head on your shoulders, and that you will email them every week. Then go and have fun and get an education!!
