"...But do you agree that parents should have the power, via their genetic relationship to their kids, to control them, and even force them to live with their parents if the youths are unhappy there? Straightforward question...."

That question is so chock full of loaded terms that it would be disqualified from the "Most Loaded Terms In A Sentence World Championships" for being too fucking loaded!

UNDER NO CIRCUMSTANCES SHOULD YOU TAKE THE DEFINITIONS OF A MR. D. ISSIDENT AS HE KEEPS CHANGING THE MEANINGS TO SUIT HIS OWN SECRET AGENDA, WHICH IS TO "LIBERATE" THE "YOUTHS" SO HE CAN GET INSIDE THEIR KNICKERS. A NOBLE CAUSE, BUT HONESTY IS REQUIRED!

I agree that parents have the responsibility to look after their own children from birth to aged 16, a reponsibility which includes feeding, clothing, keeping safe from danger, teaching, guiding, nurturing.
This responsibilty is coupled with a gradual letting go, as the child becomes more independant and grows to adulthood.
