You will lose, I would first look up what sophism exactly is before considering a dual.
So yeah, apparently I did not pay attention at philosophy class at all. The way the word "sophism" gets thrown about when it comes to political debate is sickening, especially when we equalise it with immorality. It's not comparable, as the greatest sophist of them all (Socrates) was also the greatest moralist. After all, he directly influenced Plato, who had a major impact on the Christian theology and philosophy.

PS. I dislike Plato, though.
