Because if you're wrong, asking why doesn't really help you, You will highlight blindspot and that's all.
Why is a trap.
So, another reason why they end debate quickly is that you created highly asymmetrical situation, in which you don't do the work of "being able to explain why". And of course with enough of why you will reach their limit at some point without exposing yours.
People who are not experienced negotiators will realize what is going on, but wont be able to turn the situation around.
If the conversation leads to specific examples, lessons learned or a deeper explanation then it can be a great learning experience.
