Gibson might be guilty of many things, but "afraid" is not one of them. Actually the booing would have given a boost to Gibson and his movie. Already many people, including those who are no big fans of Gibson, are outraged at the false attacks on him.
Roth comes across only as a liar.
Already many people, including those who are no big fans of Gibson, are outraged at the false attacks on him. I wish that were true but so far to my knowledge only three Hollywood stars (Robert Doney Jr., Chuck Norris and forget the third) have spoken up on Gibson's behalf. If he appeared at the Oscars and people started booing, no one would defend Gibson. They'd be too afraid they'd never work again.
