Someone may agree with MH on various points, but not necessarily *ALL* points. Some people may find a lot of his information information useful, while also disagreeing with some of his other information or beliefs. This isn't specific to UT. Someone might swear by Vitamin C or Colloidal Silver , yet agree with MH on various other points (like UT being bad!), or vice versa, someone may strongly agree with UT, but disagree with extracted/concentrated Vitamin C.
Saying UT'ers (or practitioners of anything else) have "no place" in his forum, is kind of stupid. There may be people who have found a lot of benefit in UT, but also find a lot of MH's other information useful for their lifestyle. It would make sense to me, for him to be grateful of the fact that they're interested in any of his information at all, and I would think he would welcome that interest, and accept that some people like to think for themselves and make their own decisions based on the information being presented. But instead, he seems to be saying: "If you don't blindly agree with EVERYTHING I say, then get out, you have no place here"
