It's always the oppressed who are expected to be precise and careful with their words or they are immediately punished. The punishment is immediate. They lose their jobs, their careers, their reputation. There is no second chance:
Marc Lamont fired for using a 'sensitive' phrase to demand equal rights for Palestinians
Steven Salaita fired from his tenured academic position because he tweeted in anger about the Gaza slaughter where the bodies of dead babies were being stored in ice cream freezers because there was no more space. But of course he had to be precise and careful even if he is angry.
Norman Finkelstein who lost his tenure bid because of his support for Palestinian rights
The Texas Speech Pathologist who lost her job because she would not sign an anti-BDS statement.
These are just a few of the many examples of Palestinians and Palestinian supporters being targeted because they gave a voice to the oppressed.
On the other hand, American media, senators, Presidents, congressmen, officials can say any number of terrible shit about Palestinians and nothing will be done.
That's the nature of the world we live in.
