The proposition of this speech may be one of fact, value, or policy. The topic should focus on a current, controversial issue with two defensible sides or points of view. Alcoholism, pollution, or littering should be avoided because they represent one-sided issues. However, topics such as euthanasia, assisted suicide, the driving age, capital or corporal punishment, prayer in the schools, not guilty by plea of insanity, and many, many more qualify with two defensible points of view.
