Is he doing more harm than good? or more good than harm? Thats the question. This same issue has come up with MH more than once.
The answer on both account would be probably more good than bad, so let it be I say. Both are older stubborn men, they ain't gonna change, it just aint' happenin. If it bother you, do what I did with the MH forum, just stop visiting it.
His protocol has helped a lot of people. Its better to have a flawed person giving advice and encouraging others to seek health than to have no one doing it at all.
There are only so many Andreas' in the world, he was always the perfect gentleman. Sometimes you just gotta take the bad with the good, or reject the whole thing. So be it.
