Regarding the New Zealand mosque mass shootings yesterday: why does history repeat itself?

Several thinkers have said that history repeats itself, although always with variations. Why?

While we certainly condemn the violence of the New Zealand mosque mass shootings yesterday, we should also place the blame for such violence on the heads of the liberals and neoconservatives who have not only promoted and encouraged multicultural/multi-ethnic societies but slandered anyone who predicated these terrible outcomes for multicultural multi-ethnic societies.

History repeats itself because human nature and the natural world have remained essentially the same since humans became humans, although with variations. Human's adapted to different environments by evolving distinctly different ethnic groups and races but human nature remained basically the same for all, that is kin-centered, gender defined, age-graded, heterosexual, marriage-making, hierarchical, ethnocentric, territorial, and even xenophobic, and religious-making, among other things, with group-selection as the primary unit of successful selection, followed by individual selection.

Cultures can operate for a time with behavior that goes against real human nature with such experiments as globalist Marxism, but cultures are eventually pulled back by the biological and genetic leash of real human nature to cultures that better reflect real human nature, and humans then work within and adapt to the natural environments they find themselves living in.

That is why history repeats itself, and that is also why the reality of human nature and of past history point toward the political/cultural solution of ethnostates, and an ethnopluralism of ethnostates for all groups. Ethnopluralism is a conservative transformation---not revolution--which is the sociopolitical or political/cultural structure most in harmony with real human nature and the natural world.

It has been mostly ignorance that has kept us from seeing why history repeats itself, not Satan. Is ignorance an excuse? The legal principle ignorantia juris non excusat or ignorantia legis neminem excusat, "ignorance of the law excuses not" and "ignorance of law excuses no one." But it has been human nature itself with its genetic tendency toward being ethnocentric, territorial, and xenophobic that has kept us from seeing that the best long term political/cultural solution for all is to allow the formation of ethnostates, and an ethnopluralism of ethnostates for all groups.
