Answer:
If people read sources they disagree with, they will learn more about other theories about the subject and, if well argued, they will develop a respectful feeling towards them.
Explanation:
Every source about any subject, even if it doesn't match our personal opinion on something, if it is well argued will create in us a respectful opinion and will help us to know more about the subject and to amplify our knowledge area. It is always a good idea to listen to different opinions ir order to grow in ours or to incorporate/change our believes.
