I find it interesting that this article mentions the capital punishment argument. That was one of the first subjects we had to take sides on in debate class when I was in high school.
We were asked where we stood on the issue of capital punishment, and then our teacher made us debate in favor of the opposite view. This was easy for me because I could see the benefits and negative aspects of both arguments. Some people had a really tough time trying to convince other people of something they were not in favor of in reality.
