Jehovahs Witnesses are the only people alive who have children and say "I love you, but if you don't do this, that, or the other, I won't"
Other cults or religions also do, for example mormons or exclusive brethren. It's the strength of a cult to make kind and good people act as heartless people just because they are told to do so.
But The rebel is right : every parent has his own responsability!
