Ah. It is because your first comment was vague. You didn't actually say what you disagreed with. If you had said, "Pointing out hypocrisy on its own is not a great way to negotiate. Let's try these other approaches instead or as well." then I think people would have agreed with you more.

Of course it was still peculiar that you brought up Japan, since it doesn't actually show what you wanted it to show, for reasons previously mentioned.
