Possibly - I would probably put more blame on the families. People know the rules when they go to an institution and they don’t have to go there if they don’t want to follow them.
A lot of the problem comes from families where the kids have parents who give them a ton of rules but don’t really teach their kids how to make good decisions before they leave home. So, the kids go out and are exposed to new ideas for the first time and start making poor decisions. If you want to understand the phenomenon more you might want to read Hanna Rosin’s book “God’s Harvard” about Patrick Henry College (My Alma Mater). I don’t agree with everything that she writes about PHC (which I think is a great school) but she does profile one or two homeschool rebels in the book and how react to the fairly restrictive rules on campus.
