The writer Roger Scruton makes the case for politics as healthy family life–with a good does of free expression, group identity, and dissent:
In families, people often get together to discuss matters of shared concern. There will be many opinions, conflicting counsels and even factions. But in a happy family everyone will accept to be bound by the final decision, even if they disagree with it. They have a shared investment in staying together. Something is more important to all of them than their own opinion, and that is the family, the thing whose welfare and future they have come together to discuss.
To put it in another way, the family is part of their identity. It is the thing that does not change, as their several opinions alter and conflict. A shared identity takes the sting from disagreement. It is what makes opposition, and therefore rational discussion, possible. And it is the foundation of any way of life in which compromise, rather than dictatorship, is the norm.
