You can be defensive all you want but facts speak for themselves. The pharmaceutical industry provide bandage fixes that lead to much deeper health problems down the line.
Having a healthy Ego does not mean defending stupidity and ignorance.
And you are proving my point exactly. People want a quick fix and not a long-term solution, so perhaps next time when you want to be snappy - add that as a disclaimer for your opinion.
Also, I would love to hear your spiritual journey over those many years. Have you shared it in writing? Always open to reading a sincere story. :)
