Everybody around the world does it. In fact, the CIA has been doing it since its inception!
We haven't ever seen a disinformation campaign that was this effective before. At least, we haven't seen one that was this effective against countries with free media and an educated population. (Though the effectiveness of this attack might lead one to question both the freedom of the media and the educatedness of the population...)
Them doing it to us may be "turnabout is fair play", but that doesn't mean that we have to like it, approve of it, or accept it.
It's funny watching people always accuse the other side of being uneducated.
If you've got an argument, give it. Save the emotional manipulation for children. (In fact, don't use it on children, either. Just lose the emotional manipulation altogether.)
