How do you differentiate between an effective debater "controlling the framing of a conversation" and an effective thinker providing a new perspective on a shared experience?
How do you differentiate between a good argument and a good idea?
I don't think you can really?
You could say intent plays a part -- that someone with an intent to manipulate can use debating tools as tricks. But still, even if someone with bad intentions makes a good argument, isn't it still a good argument?
