That would explain why in our current system the conservative faction is more like this than the liberal faction. But what I was getting at is the reason that the conservative faction is essentially singular. In a less broken system, there could be multiple conservative factions and multiple liberal factions without the sub-factions feeling needing to choose whether to band together on every single issue or be irrelevant.
They could dynamically band together on a per-issue basis and have more reasoned discussions focusing on those issues instead of making sure to pronounce “shibboleth” correctly.
