Debate is an important platform to get to know of various perspectives and hence improve our way of looking at any topic, incident or a person. The more open minded you are the more people enjoy debating with you. The more open minded you are the more you you can learn from a debate.
Be open for debates, unless that's not possible at a given point of time due to time or process constraints. Be as much open minded as you can and hence enhance your understanding to the next level.
