just some general comments. no meaning to them in particular
when there's a discussion, the conditions present are harmony, positivity, agreement (even agreeing to disagree). no holding on to any particular view, ability to discern the common and uncommon grounds and respect for any other particular form of view. in practicing any discussions that allows one to wisely respond without inciting arguments are beneficial.
in a debate, there is often holding on and assertion to a specific viewpoint (even the assertion of buddha's view). atmosphere becomes disharmony, negative, disagreement, lack of respect. in practice only some are able to benefit from such conversations cos its not easy to map the territories.
well then again, these are just another dualistic views, pay no heed
