My view on this. I have been a long time reader of Kiyosaki and have listened to many of his radio shows.
First, I don't think that Robert has been introduced properly to the real word, anarchy.
As to his response, he has been taking heat for going against the grain longer than any of us. He has had many more lawsuits like your Gults Gulch fiasco. So many that you wonder if Kiyosaki is really legit.
Take into account that his co-author is now the president (who is being attacked by everything left), and the guy is probably taking flack on everything, everywhere.
If I was under that level of stress and scrutiny, I would probably have a short trigger too.
Also, his income is wed to the banking system. Getting loans to pay for loans to buy houses. So, the guy must have a lot of cognitive dissonance when it comes to the evils of banking. (a strong topic in anarchist circles)
