Many individuals are taught to not really have or express an opinion at all. If this is so, it can feel really uncomfortable to be around someone who not only has a strong opinion, but willing to clearly articulate this fact. And especially so if he or she finds lively debate enjoyable, even seeking it out unsolicited. This can be for a number of reasons:  Cultural differences: Some cultures downplay frank open discussion on sensitive matters, while others treat it as rude not to talk out things. Gender upbringing.

One personality type is not better than another. The personality type well suited to being a judge may not be the same as one best suited for being a minister. Different people do not see eye-to-eye on the same things. And sometimes this can be difficult for some people to handle. It seems so wrong for another person to feel the way he or she does! But here are some things to remember:  Having a different opinion does not mean he or she is less than you. The opinion is not the same as the person. One can have the same opinion as you, but that does not necessarily make the person better than someone with a different opinion. Listening does not mean agreeing. Simply listening to another person's point of view does not mean you agree with him or her. It just means you are hearing him or her out. You do not have to engage in every argument you are invited to. Some people live to argue, but...
