This is my very recent experience with this phenomenon on steemit..
Someone said "So what" when I commented to their article (about providing your physician with your genome sequence, as it has become increasingly cheap) that doctors receive little to no nutritional training and purport vaccines as efficacious and chemotherapy and radiation, known carcinogens, as cancer treatments. When I showed that googling "radiation causes cancer" shows the first result as saying "not all radiation causes cancer.. learn more" from the "trusty" cancer.org, and when you follow that link and consider the information presented there, you realize there isn't anything else to learn more about cancer not being caused by radiation, but a whole bunch of stuff admitting to the fact cancer being caused by both radiation and chemotherapy, to which the user told me that I was on a bad path, and wasn't being rational..
All I could do was question her conclusion that I wasn't being rational, but I doubt that I'll have a response. I questioned the doctors' trustworthiness and general knowledge about nutrition and diet, a very dangerous attitude and here I am wondering if what I said would even be considered.
