Richard Dawkins and Sam Harris have frequently been caught in the crosshairs of campus and media censors, like the article linked below.

You would also do well to read what has happened to Ayaan Hirsi-Ali, not so much as the death threats from Muslims, but her treatment at the hands of Western liberals.
