Can people who follow Christ have a disagreement? Can they be mad at each other? If the answer is yes, then what about "love"? Where did the "love" go? The answer to the question is yes. Just because someone has been washed in the blood of Christ and has had their sins forgiven doesn't mean they stopped being human. We still have opinions, feelings, and emotions and many times we feel as though ours count more than others! In fact, two of the strongest Christians that ever lived had a huge argument and it got so heated, they decided to part ways and do their own thing! That's right! Paul and Barnabas, both love God, both gave their lives to serving God, had an argument over John Mark and, because of their disagreement, decided to go their separate ways. Did they stop being a Christian? Did they quit "loving"? No! In fact, they continued to serve God and love one another, but they did decide it was best for both to do their own thing. It's all in how we act and react when a disagreement happens...because trust me, it WILL happen!
