Politician: Suppose censorship is wrong in itself, as modern liberals tend to believe.
Evidence
Suppose censorship is wrong in itself, as modern liberals tend to believe. Then an actor's refusing a part in a film because the film glamorizes a point of view abhorrent to the actor would be morally wrong.
But this conclusion is absurd.
Conclusion
It follows that censorship is not, after all, wrong in itself.
Evaluate
There are two reasoning structures at play in this argument. The conditional reasoning takes the form of a contrapositive, which is used properly. The second is the comparison made between an actor refusing a part and censorship. On this second issue, the argument assumes the two issues are comparable.
