I think it's a difference in how we define words. If we focus on our common ground, first, then we are more likely to listen to each other. To a person who identifies as centrist, a person who calls themselves liberal might appear to be on the fringe of society IF the so-called centrist (who may even actually be liberal) is within a community where they are surrounded by more conservative voices.

Being with my husband has taught me that how we individually define words matters a lot more than we think. He and I grew up in very different circumstances and will often argue different points and then get extremely frustrated at each other for not understanding what we mean. Sometimes I'm thinking "what is he saying, that has nothing to do with what I'm talking about" only to realize that the way he defines a word, phrase, or idea is completely different to my definition.

If you want someone to truly listen to you, you first have to be open to discovering what's important to them and how they are expressing it
