People who subscribe to the "diagnosis" of ADD are virtually always liberals. They subscribe to the reigning orthodoxy. Been seeing it for years and years in my practice as a shrink. Oh well.
This has nothing to do with the psychological over-diagnosis of ADD. It has to do with not saying no to your children and screwing up their character. It's labeled as Discipline Deficit Disorder as a tongue and cheek poke to those who need to put everything in tidy little diagnostic boxes. As in "I'm sorry, I can't discipline my children because I have DDD." Or "My children have really bad behavior because they are suffering from DDD because of me."
Back up and try reading it again with that in mind and see if it doesn't change the perspective a bit.
BTW, I see you're new here. Welcome to Free Republic.
Back to work for me.
