The idea behind naturalism from a political perspective is everything works from natural preset, that all things will remain natural, from markets, to industry, to the running of government. Unfortunately it has a tendency to breed hierarchies, "meritocracy" and dominance as a form of natural selection. It's the foundational reasoning of nationalists, tankies and the old Catholic church, albeit "under god", not to mention racists. Us versus them, enemy mentality, it's all weaponised pack instinct.

I feel Humanism is juxtaposed to this, because it focuses on the possibility of humanity through the individual. It's not being humanitarian, as that stems from altruism.

Humanism from a political level poses that society and the individual must create environments conducive of bringing out the best in everyone and to generally create humanized environments as a base necessity. Like for instance a prison system that gives prisoners each their rooms and bathrooms, or a schools that meet the needs of students, or even national funding of religious organisations from a cultural perspective, like Mosques and Churches.

To put it bluntly, Martin Luther King Jr is a humanist icon and humanism is the foundational philosophic model of Nordic countries such as Norway. It's even written into the Norwegian constitution as a foundational tradgional value.

However, naturalism becomes normalised if you're at war, or when facing a major existential opressor like with CRT in the US, during economic collapse, etc. Then it becomes almost unavoidable and understandable even. But it's still the core philosophy of authoritarianism and is something people have been trying to get away from for millennia.
