I think in a lot of cases it's more that: 1: We know the assumptions. 2: We know the differences are often intractable (I will never relent on full LGBTQ equality, for example) 3: We can't just split off and do our own thing because we need each other for civilization to function, so we have to deal with them. Some of us can avoid dealing with it by moving to the city/suburbs/exurbs where there's more unity, but that just postpones dealing with the problems we ran from. Eventually, elections happen, and you realize putting 50-5000 miles between you and that person who finally motivated you to leave didn't actually resolve your conflicts.
