Oooo I actually love this subject (passive voice being used to cover up the crimes of those in power).

The historical marker outside the Paul Robeson house is a really good example.

>[Robeson's] career suffered because of his political activism...

This makes it sound like he was bad at time management or something, and he neglected his work in order to do activist stuff. But the reality of course is that he was blacklisted by the government for being a socialist and a peace activist.
