Well that all can depend on how the person debates. One can learn from a debate from others. Some debates can be "healthy" at times to let out what you want to say. Look at Congress and the Senate for example; they debate on new law to take effect. HS thru college students debate to learn on issues within their class. To question is health for people, if we did not have debates one would not learn. But this is just my take on it and IMO only and how I see it.
