The key issue that relates to political division: > As a general rule, the more political and emotional and social ties we have to an idea — the more an idea matters, in a deep way, to our sense of ourselves — the less likely we’ll be to let it go even in the face of strong evidence it is false. The more you "are a progressive" or "are a conservative" (or whatever ideology, these are just examples) as part of your identity, the less open to reason you become. Ideologies give concrete answers that you can just point to whenever a hard question is raised - but more often than not these concrete answers are inflexible or only partially useful.
