Agreed. A friend who almost died before getting a liver transplant was talking to his neighbor who had just moved in. His neighbor said he was a “California transplant”. Very insensitive.
If you did the slightest bit of digging, I think you'd find that 99% of people mean no offense, and would be deeply apologetic if their "transgression" were brought to their attention.
If you're sensitive enough, you'll find yourself offended all the time.
