Individual = a set of natural inclinations to act in some manner, a pattern of behavior
Group = a collection of individuals
Homogeneous group = a collection of similar individuals
Heterogeneous group = a collection of individuals that have one or two things in common (e.g. need to survive) but that have nothing else in common which is why such groups tend to be hypocritical, everyone secretly hating on everyone else; also known as rabble
Group identity = shared pattern of behavior as evidenced by the history of the group
Heterogeneous groups have no identity, they just pretend they do. Think of Christians, modern nationalisms, liberalism, etc.
Why is violence necessary in order for a group to preserve itself? Well, in order to continue to live the way you want to live your life (as defined by your instincts, drives, habits, interests, passions, customs, tradition, etc) you have to eliminate every obstruction on your path. This requires some sort of violence. If you don’t do that, if you don’t defend yourself, you cease to be who you are and you eventually die.
Homogeneous groups degenerate into heterogeneous when their defenses become weakened. Basically, that’s how they die. Again, there are limits to everything, so groups too, like organisms, have a lifespan, going from birth and young age over maturity to old age and death. We’re sort of dying right now.
It’s interesting that heterogeneous groups preach homogeneity more than anyone else. And they do so on a universal level by coming up with some entirely artificial, made up, pattern of behavior that they then try to enforce onto everyone else. Whoever doesn’t comply is shamed.
Pacifism is one such entirely unnatural pattern of behavior.
Asceticism, i.e. expecting people to have fewer needs than they really do, is another.
