Usually this is the point when someone goes “but debating is a great way to learn!” and I cannot stress enough that whatever learning gains there might be in individual cases, these are clearly offset by the terrible results of framing anything and everything as a political debate. Look around you!
Also: the "debate" framework is an impediment to learning how knowledge production happens. When I taught basic research methods to undergrads, they'd often enter thinking there were two sides--and only two sides--to every topic. Many struggled with the notion of multiple perspectives.
But grasping the intricacies and interaction of claims is essential for things like doing a lit review and writing a research paper! The body of research about a given subject can't be slotted into some facile for/against binary. I blame cable news.
