Maybe contemplating the draw backs of debate helps:
Self-conquest is far better than the conquest of others. Not even a god, an angel, Mara or Brahma can turn into defeat the victory of a person who is self-subdued and ever restrained in conduct.
However, debates have benefits such as testing the consistency of ones own views. Also solving disputes through debates is better than resorting to violence or hate speech. Also debates can reveal the necessity of good intentions in investigating a truth with the help of another. Some statements can be technically true but serve to deceive absence good intentions. Also debates are manifestations of the uncertainty in conditioned phenomena. It also reveals how conventional reality functions and the temporary feeling of security we gain when we persuade another to agree with us. We get the feeling that the more we get people to perceive reality and to behave through the lens of a certain idea, the more we are heading toward a more certain and a more harmonious future. This is probably why, being a good debater is associated with status among social beings.
In a religious or spiritual community such as a Buddhist forum, discussing and debating are the primary vehicles of learning. There are aspects in us that can be cultivated in positive ways with the help of wise friends, such as our competitive nature and our desire to be right. There is nothing praiseworthy in losing a debate. When you observe our nature, our engagement with others is constantly negotiated since childhood. Even the limits and the status of the Buddha's authority is subject to negotiation among the unenlightened from a mere spiritual friend to being the one who knows.
In general, how we view things depends on where we are on the path. What can be beneficial at a certain point can be a hindrance at a different point. The individual practitioner is the ultimate criteria in my opinion.
And the Blessed One addressed the bhikkhus, saying: "Behold now, bhikkhus, I exhort you: All compounded things are subject to vanish. Strive with earnestness!"
This was the last word of the Tathagata.
