@mloxton I disagree with this. If you go into a debate with the right mindset, it's one of the greatest ways to learn new facts and perspectives. For example, most of my knowledge of 1A jurisprudence comes from being proven wrong in Twitter debates and learning something new.
While not everyone approaches debates with such scholarly ambitions, I think writing them off as "childish" is going too far in the other direction.
How can we truly define our own ideology without it being regularly challenged by our peers?
