4. (E)
Question type: Identify a Flaw
The author incorrectly assumes that an actor refusing a role is an example of censorship. Censorship involves the suppression of a person’s idea or speech _ an actor does not censor by simply refusing a role. (E) accurately represents this flaw.
(A) goes outside the scope of the argument.
(B) is an attractive answer. The author does have a negative attitude about modern liberal beliefs, but he does not use the term "liberal" in order to discredit the opponents (he uses the term "absurd").
(C) goes outside the scope of the argument.
(D) is incorrect because of interpretation.
