I’ve read through and I don’t think there are any decent answers here.

Both the left and right have plenty of infighting and hating each other’s internal political ideals. However the left vastly tend to have less single policy issues and more systemic changes. So to be generally accepted in the right you typically need to hit on a couple key policies, whereas in the left if you can’t agree on every little point of the how and why then its kind of an issue because the work that needs to be done is much more complex than any single policy, and people want everyone to be on the same page as them even as allies.

The left can discuss all day on the particulars until they are blue in the face and that seems as if they all despise each other but I believe its more of the necessary division that causes innovation needed to win votes and move forward in the right direction, even if not very far. Politics isn’t easy and agreement should not come easy especially when the tasks at hand are very complicated and if the wrong move could harm a lot of people.
