4. NUANCE
The concept of nuance is present throughout. The nuanced story is the more difficult story to tell, but it is also the more important one.
Controversial issues always have multiple points of view. And although we do not argue that the truth lies perfectly in the middle between two arguments, we do argue that, at the very least, it is even less plausible to reduce it to a black-and-white juxtaposition.
By staying away from black-and-white fallacies, by allowing nuance to enter your personal convictions, the possibility to build bridges will always remain, no matter how wide the canyon between you and the other individual might appear to be on first instance.
5. DOUBT
Having doubts about a certain subject can be one of the most important components of a debate. Those that doubt are the ones that can tip a debate in the right direction. Whenever two parties fight, it is those who doubt that have already been considering the arguments of both sides for a long time. These people are the ones who are capable of looking at the issue from multiple perspectives and understand where the arguments, and the people promoting them, originate from.
When the doubter decides to take the stage, to engage themselves in the debate, it is the moment when both parties gain a new and serious opportunity to find a solution and finally move on.
