What kind of people do I dislike?

I don’t like the people who do not accept other opinions and who think his/her opinion is the best. I cant help it. People make an idea standing on a point of view. For example, there is a person who is a teacher and has a family. In that case, his ideas come from two viewpoints: teacher and father. Its hard to consider from students’ viewpoint or children’s viewpoint. I don’t like the people who do not even realize this fact.
