As far as I can see, our Brazilian friend simply had a simple question. It is a valid question. He did not have the intention to start a debate with someone.
We should be more tolerant and allow people to ask questions. Even questions that may seem to challenge the views of majority of people in the forum. That is the way to learn. I think most of us were suspicious when we first started using Miracle-Mineral-Supplement .
Brazilian friend: I hope you will stay in the forum. Whether you will use Miracle-Mineral-Supplement is your decision. May be you will try it for a few days. If it works for you, it is wonderful. If it does not work for you, throw it away and move on.
