[request] Info on Homeless/Run-away/Kicked-out Youth

From a fellow student:

Hey peeps,

I am writing a paper on homeless gay youth and want to argue that parents who force their children to leave the home on discovering the child's sexual orientation should be criminally and civilly liable. If y'all know of cases and books on point please please bring them to my attention -- I am in need of the help.

Thanks and peace, J

If anyone knows of interesting/relevant sources off the top of their head, please take a moment to comment.
