I often wonder what kind of life a person must lead who spends hundreds of hours trying to tear others down, while at the same time selling his own stuff as he does it...
[I have no overarching opinion or RK. Some things in his books are great, some are unclear or wrong. I have my own “rich dad” who has mentored me. I also have my “bio-corporate dad”. I’ve learned from both. ]
If the people he is tearing down are charlatans, and the advice he gives is generally good, then there is nothing wrong with this, and he is in fact performing a public service as well as giving people value for the money they spend on his books.
I recommend reading everything Reed has to say about Kiyosaki (and some of the other "gurus") with an open mind and forming your own opinion if what he says has merit.
You might also want to check out his general piece on real estate B.S. detection and see if there is anything in there with which you disagree.
