So your source is: “this guy I know said someone told him something”?
My source is people I know who are honest with great integrity. I asked them and we discussed it.
Fact is they were told. Fact is you don’t know them.
Fact is they are likely a more honest source than NY Times, WaPo, or many other sources of information.
Do I care what you think about my source? No I don’t. Feel free to live in your ignorance. shrug.
PS. As I also noted up thread. The caution had nothing to do with magnetism.
