This is wrong. I don't give a fuck about any bullshit about preserving the family. I just don' t see any difference between divorcing a rotten spouse and divorcing a rotten parent. Parents who disown their kids should be brought to bear financially and also should be subjected to the same public humiliation as deadbeat dads and moms are today. Nobody forgets what they once were quicker than adults.
Kids have no rights in the supposedly democratic United States.
Only those who already have their rights can grant them. Until such enlightenment happens, here's some suggestions for those disowned by their parents. These ideas are untried and unproven by me, but give them a shot. Try to get your parents' friends, your aunts and uncles, and your parents' co-workers on your side. Let your parents feel some peer pressure.
