Sometimes when we observe another person discussing their views, it can be difficult to understand how they came to that conclusion. More and more, the reason for this phenomena is that the person has arrived at their conclusions through poor thinking. Our society has in fact entered into an era that is marked by, among other things, the near abandonment of logic by a large portion of the masses. Because of this, it is becoming more difficult to convince people through sound argumentation; instead, they require an emotional appeal that opponents to Christianity seem to have mastered.
