have a different opinion than that another person is formal in expressing strong differences, such as what officials think or what most people think to do the opposite of what a person, a set of rules, etc., says you have to do it because you don`t agree with them. when two people are drawn by daggers, they feel very angry with each other when different ideas or opinions conflict, they may not all be right or do not all happen when one statement, a piece of evidence, a story, etc., contradicts another, that they do not agree and that they cannot be true.
