How many times have you seen a debate, where you loved and praised the person you supported and were annoyed by and scorned the person that you were not supporting? This is because debates are by definition constructed to produce this result. The point of a debate is for each side to use any means to persuade the other side until one prevails with a “superior context”, rather than to find understanding or even common ground in one another’s viewpoints.
Debates are about winning an argument, rather than creating mutual agreement, even if the agreement is at least: to agree to disagree. If someone listens to understand the other side, it’s in order to find ways to argue against it.
