"It should be labeled"? By whom? And for whom? For people too stupid to figure it out the difference?
No. "It should be" shouldn't be. All the media corps need to do is admit they intentionally deceived the public for most of the last century and they still have a bias. Then go on from there.
It should be labeled. Sheesh. You are one of THOSE people (the kind of people who have created a civilization with so many laws, rules, and regulations that you yourself cannot live a day in your miserable life without accidentally committing 3 felonies).
