Yes, and if the comment had said "It's not legal anywhere except Iran," then there would be no confusion or disagreement, because that is an accurate correction.

But people do advertise kidneys for sale even in countries where it is not legal. It does happen in many countries. Saying it doesn't happen is different from saying it isn't legal.

Which is why I said they could have been more clear. I was wrong about who said it, because I didn't realize I was replying to someone else. Otherwise, I stand by what I said.
