You can never win an argument with a negative person. They only hear what suits them and listen only to respond.
In arguments, what we aim is not to decide who is right and who is wrong. This is also a chance for everyone to just look at themselves and more understand the other.
However, this good purpose cannot be reached if you are in an argument with a negative person. That person will default that he/she is always right, and the other is always wrong.
This thought makes them have a prejudice to those who opposed them. They only listen to what is good about them. They ignore every comments which shows their weakness. They only listen to what they want to hear.
If their partner gives negative comments about them, they just do not care, do not look at themselves. They will try to defeat the partner’s opinions, even criticize to lower the opponent. They do not want to improve themselves.
As a result, these negative people learn nothing after the debate, but also cause discomfort and aversion to others.
