Neutral arguments avoid using you statements and therefore can assist in avoiding being perceived as offensive or indicating that you believe that your competitor is unreasonable.
The benefit of using neutral arguments to express oneself while in a conflict is that the conflict does not get violent or offensive when neutral arguments are used.
A neutral argument does not blame the other person who is involved in the conflict, therefore, it helps in reducing the tension between the persons involved in the conflict.
In neutral argument statements having 'you' word is avoided which shows that he is not offensive and does not want to escalate the problem. Therefore a neutral argument can result in solving conflicts.
