Zero respect
What is respect, technically? Should we respect each other by default? In order to answer this, we need to return to our roots. When one alcoholic approaches another alcoholic and asks - "Do you respect me?" - What does one mean by that?
It's quite obvious that there are several stages of respect. At first, we don't know each other and don't see any reason to apply any respect to our non-existent relationships.
Then we meet and may realize that our behaviors are aligned. We have the same values. Now I respect you and you respect me. We can drink together. We can share a table.
If you bring an additional bottle of cognac, you invest in our common cause. You're a real man! You deserve more respect.
But the moment you steal my girlfriend and go against my values, I'll punch you in the face. You just lost your respect and you shall never be forgiven! Unless you got another bottle, of course. Maybe you can earn your respect back. We'll see.
We can treat respect as a special case of a selection among our programs. It's directly connected to a will to power. The words "I respect you" can be rephrased as "I would like to stick around, use your help, learn your tricks, and get better chances of achieving my own goals." All individuals with a reality checker in their design can come to this strategy.
Respect isn't reserved for relationships within the same species. We can apply it to anything that we want to keep with us in order to progress with our behavior. We can respect nature as long as it provides resources for our needs. We can respect our swords, our legacy, and, naturally, ourselves.
There is a common idea that every man, every animal, and every zombie deserves respect by default. It doesn't make any sense. We have conflicting values by design and can't all be aligned.
People often confuse respect with politeness, but shared rules for manners exist independently of our carefully selected programs. Personal respect doesn't make you a gentleman, and you most definitely can behave like one with zero respect. Every nobleman knows how to humiliate one's rivals in such a polite way that they won't be able to parry that without losing their pride completely and will have to retire.
Collective rules, including these public manners, may help us to achieve certain goals regardless of our incompatible behaviors and local alliances, but we have to be clear about them and don't just blindly follow old instructions only because our ancestors said so.
