"Are you sure you can't have dairy? Why don't you try it again! Who diagnosed you? Oh! That's not a *real* Dr. They did the wrong test! That test is not legitimate! Sorry to tell you this but you just wasted your money! You can't believe those test results. Too many false positives! On and on and on like that. Have even seen people attack other people for their symptoms and try to tell them that they are psychological and can't be related to food!"
If anyone said any of those things to me they would be shown the door. RIGHT NOW!
Thankfully I don't get a lot of that in real life. I do get some. But I have seen it a lot on the Internet. I don't care if they don't believe in the testing methods I used. I only know that since I stopped eating the various foods, I am no longer sick all the time. Lots of maladies cleared up. So clearly to me, I can't have those foods.
