Why are people so down on the Natural Remedies book just because the author(Kevin Trudeau) was a felon?

Yeah, so he was a felon.. so what? The stuff in his books arent things he made up. In fact, if you pick up one of his books he sites the sources (which are real doctors from all over the world) who believe these treatments. In america we have all been brainwashed to believe that only the "medical" doctors can help us with all their drugs.. but thats crap. I have been seeing an herbal medicine doctor for 11 years. For 16 years I suffered from migraines. He gave me a little bottle of some herb (it was 11 years ago, I dont remember what) and I haven’t had one since. I read thru trudeaus book and havent found anything I couldn’t find research to back up. People who are in denial that natural cures work have been brainwashed by society. They may take longer to work, but that’s because they actually work, they don’t mask the symptom. Think about it, you take asprin for a headache..why? Is an asprin deficiency causing it? You mask the symptom, but never cure the cause.
From what I gathered what the book said was that viruses could be cured. And before anyone says it, it also says that the sun doesn’t cause skin cancer. And this has been proven over and over. All the crap we put in our bodies causes skin cancer. Thats why people who live in warm climates, out in the sun, in other countries don’t get it nearly as often. They don’t stop at McDonalds every day. They eat healthy and that keeps their bodies healthy, which keeps their skin cells healthy.
