Through the use of ethos, King describes the "status quo" of the city of Birmingham, their beliefs, and the characteristic spirit of Birmingham. The ethos encompasses all the little bits and pieces of segregation because the ethos describes the community as a whole. He says, "Since you have been influenced by the view which argues against ‘outsiders coming in.’" and "Never again can we afford to live with the narrow, provincial ‘outside agitator’ idea." This tells how the community thought of black people as "outsiders." The use of ethos benefits King's stance and position by pointing out the flaws in the "status quo" of Birmingham.
In using pathos, King acquired the ability to emotionally connect to the reader and evoke pity. This made for a stronger stance on his part. King even starts his letter with the use of a pathos saying "While confined here in the Birmingham city jail..." This immediately makes the reader think of the reasons King became incarcerated and of how unjust the reasons were, which made the reader upset and feel bad for King. More upsetting pathos is used as well, such as "We realized that we were the victims of a broken promise" and "Our hopes had been blasted, and the shadow of deep disappointment settled upon us." These become very useful because every single person has had that specific feeling of getting your hopes up only to have them shot down plenty of times before. Any
