Don't know much about your circumstances but I felt the same way about Water Fasting in relation to my family, and now I am finding out about nutritarianism / nutritional healing as well.
Reminds me of a past life when I sold cheap phone calls, in the UK it had just been deregulated. In those days people didn't believe it was possible and you would waste time arguing with them. We had a very good motivational guy, he used to say, "don't waste time on them, it's their problem, just say NEXT" and move on until you find someone that says "wow, this is great". That way you will "sell" to more people, or in your case make well, I presume. Eventually they will catch on, when they feel left out.
I feel like that these days with what I am finding out. And Dr Fuhrman also told me that I wouldn't change my elderly parents eating habits because they are set in their ways. He was correct.
