This has been a problem for me though.
I debate strongly because if an idea is accepted or rejected, I want to be confident in that decision.
This is often construed as aggression, which is not helpful.
A coworker once commented to me that he was surprised how easily I am willing to accept a new point of view, because given how strongly I debate, he figured I would never change my mind on anything.
In fact it's the opposite: if someone makes a good argument for something that runs against my previously held opinion, I will replace the old opinion with the new one.
