I had heard about this in my distant past, but years away from the automotive restoration scene had allowed my memory to lapse.
So thanks from me and (I’m sure) others who were thinking like me. I don’t see any reason to be upset or offended by the discussion. It’s just good, helpful information that we can choose to use… or not. We are all responsible for our own bodies, and having the info gives us the ability to make good decisions. :-)
