That is not double standard.

Targeting a broad group is in effect conceptualized it, you shouldn't try to personalize that kind of statement. Do you know there is a special name for these people ? Whistleblower. They are the conscience of the society.

Just make an analogy using your logic, anything negative you say about US can be interpreted as an attack on the country and the American people therefore can be punished as an act of treason. It happened before, and it could happen again.
