[Belonging to a political party lets us be lazy as the decisions are made for us..."Liberals like frogs legs. Conservatives read stories about dairy. etc."] This is true for low-level thinking, and current human political parties. At the higher hierarchical levels, there are many people who think in a rational way about politics. A party comprised of people who agreed with and fully understood Harry Browne and Frederick Hayek would be a good thing, and perhaps they'd be able to reduce human violence in the world.

[Belonging to a political party lets us have a sense of belonging. On the other side of the coin, it gives us the sense of rivalry. Humans need rivals as much as they need comradery. "My life would be so much easier if it wasn't for those darn so-and-sos."] Again, true of low-level, uneducated, violent brains, but not inherently true about political alliances.

[Belonging to a political party fills our minds with much-needed obsessions. "My life would be so much easier if it wasn't for those darn so-and-sos," (murmurred during bothered and sweaty sleep).] Goals do the same thing. Some goals are legitimate, others are not. It's the same with political goals. If you're trying to prevent the Jews from being murdered in nazi Germany, that's a laudable political goal, and you'd be on the side of right. ...Especially if you knew how best to do it. Maybe you'd fail, because the majority is too much against you, maybe not. In a similar modern case, maybe you know how to leverage technology to avoid violence.

[Belonging to a political party lets us feel we have a secret everyone is trying to figure out. "Truth is such a burden on us elites."] Or, maybe we do have truthful ideas. We only know by putting them in conflict with other ideas, via argument, debate, research, and exploration.

[Belonging to a political party gives us a sense that we are impacting the world. "My party will achieve peace in the world by trampling down all those who stand peace's way."] If we can give evidence for why this is true, and that evidence withstands scrutiny, and reasoned investigation, then maybe it is true. Most of politics seeks to impose ideas on others with violence, so that's a big hurdle to get out of the way, before proceeding.
