YABU, but you're not unusual in what you think. I can recall many times when my friends thought I was nuts, but, a few years later, I notice them adopting my strategies all the time now.
I think it does sound quite alternative when you give it a cursory glance, but once you look into it more it makes a lot of sense.
People seem to think it's about being so liberal that you just let your children go wild. It's really about communication, respect, teaching and demonstrating the right way.
In many cases the UP way takes longer to achieve results than threats of the naughty step, but our (UPers) widely held belief is that it will pay off with a 15 yo who's not going to respond to the naughty step but might respond to the unconditional love, reason and understanding they have always known.
And, more tongue in cheek, we also believe time spent on UP parenting now will save time in prison visits to our kids later...
