We will have to agree to disagree, Ricky. There is an enormous amount of research and information out there at non-partisan research databases (like PubMed) that substantiate medical research through firm evidence and peer reviewed (and scrutinized) findings.
Moreover, there is no legal requirement to include a disclaimer. It is included or withheld at their own risk. If these claims and supposed "cures" were real or undeniable, then no disclaimer would be necessary.
I am curious, however, upon just what and where you are basing your assertions. What evidence, research and information substantiate the claims about a "cure for AIDS?" How is this "research" any more valuable than the enormous amount of medical research?
Why should someone believe a guy like "Dr. Coldwell" over the overwhelming majority of medical researchers, scientists and doctors. Remember: This isn't "theoretical" medicine. This is a field that is reviewed by credible OBSERVATION and exhaustive CASE STUDIES.
You see, the notion that the FDA is "wicked" and the medical industry is purely motivated by profit is merely a CONSPIRACY THEORY. There are plenty of good, Christian doctors and medical researchers out there. There are also other people who entered the field of research who make less money than you would think (especially in medicinal research).
When it comes to cancer, there are "probability rates" for successful "outcomes" or "cure" that are announced by doctors regarding various possible treatment regimens. Doctors also explain the side effects of such treatment as well. Not all cancer treatment is based upon chemotherapy or radiation therapy.
There are other methods of treatment -- from surgical removal of tumors to stereotactic radiotherapy that is almost entirely non-evasive and with few side effects. These have produced amazing advances in cancer treatment rates -- and has turned many 100% fatal diagnoses into a simple, non-life altering treatment that prolongs life and often results in amazing "cure" results.
Again, I would recommend that anyone who has a major illness or disease to get second and third opinions. However, when a supposed "Dr" like Mr. Coldwell states his claims while simultaneously selling products and advice, I would carefully inspect those claims with prayerful (and smart) diligence.
