I have learned from Kate from anime that acceptance is actually a military strategy far superior to "single minded unity".
Whats it about?
Acceptance increases number of your allies naturally, by reducing number of enemies by reducing exclusion and increasing support.
To make it simple, there are many types of people in the world.
If you accept only one type and work against all other types, you will likely have more enemies than allies.
Democrats, by accepting and supporting different types of people such as gays, trans, minorities, oppressed ones, migrants, poor...ect.
have actually greatly increased number of their allies.
If you support all different types of people, then all different types of people will support you.
It is much better to create a system where all different types of people work together, rather than forcing all to be one type.
This is also true for global dominance. You cannot force all other countries to be made of one type of people, but by giving support to all different types, you as a result recieve support from all different types of people around the world.
Democrats have won popular vote twice in a row, because they give support to many types of people, which when it sums up, adds to majority vote.
Most people support abortions, thus democrats by supporting right to abortion, support most people, which in return increases support of most people to democrats.
The simple strategy of acceptance, which dictates that all types of people should be accepted as long as they accept others, is almost like a perfect political law which cannot be countered in any way, as it goes beyond simple "go with what majority wants", but it recognizes that even different parts of society which are in minority individually can reach majority once their numbers are summed up and once they are united.
Thus, by giving each type of person something which that person wants a lot, the support is gathered from all groups in society, and majority vote is secured.
From this point, democrats cannot ever lose a popular vote as long as republicans exclude so many people from their ideology.
