In Ancient Greece being a citizen with duties and obligations can be considered a social concept. Those features are not religious unless dictated by or resulting from the religious belief set.
This is one reason why the concept of religion obfuscates more than it enlightens. The idea of a 'social concept' distinct from religion is the idea that there is a clear divide between the secular and the religious. This distinction didn't exist in most societies, and the concept is generally a product of European Christianity.
Citizenship didn't derive from religion in a scriptural sense, but citizenship could not be separated from religion in a practical sense as religion was the fictive kinship that bound the community and one could not be a citizen while rejecting the ritual.
As to Genesis, that some percentage of the whole of Abrahamic faiths consider it myth and not fact doesn’t mean that the adherents don’t attribute the cause, nature, and purpose of the cosmos to a mythic entity which they consider to be true. The religious tenets are believed true and the tenets are justified by myth.
In apophatic theology, God cannot even be said to exist

Depends on who or what is assigning purpose. Who or what is assigning purpose in Marx’s view?
If a utopian outcome is viewed as the inevitable end point of History, on what grounds should that not be considered different from Divine Providence?
Not all false beliefs are Religion. That they created false narratives around evolutionary biology has it grounded in the realm of physical reality. False belief or self-deception alone does not constitute a religious belief. And for that matter, not all magical or mystical beliefs would be considered Religion. If one believes in Leprechauns, it would not be religious because it is not part of a belief set relating to the creation, nature, and purpose of the cosmos. Not all myths are religious myths.
You defined religion as "A set of beliefs concerning the cause, nature, and purpose of the cosmos, with the existence of an agency or agencies not bound by physical laws or manifestations of existence not bound by physical laws, and such beliefs are held as true by Faith and do not require empirical verification."
Naziism combined blood and soil nationalism with a Providential and millenarian teleology, this is an agency not bound by physical laws, held as true by faith and incorporating a view on the nature of the cosmos.
So it meets your criteria.
That there are social values that developed through religious belief is not in question. However, it can be argued that religion was used as justification for both sides of the civil rights conflict, be it civil rights for people of color, or women. Arguing for fair treatment is not a religion no matter how you want to spin it.
It's not simply arguing for fair treatment though, it's a salvation narrative containing Original Sin (White Privilege), virtue from suffering (intersectionality, the more 'oppressed' you are the greater your moral authority), heresy (being cancelled), saints/martyrs (George Floyd), redemption, etc...
From the Secular Humanist horses mouth:
“Secular humanism emerges, then, as a comprehensive nonreligious life stance that incorporates a naturalistic philosophy, a cosmic outlook rooted in science, and a consequentialist ethical system.”

Not a religion.
I asked you which things I said were wrong as there is no standardised definition of religion on which to judge. Of course they say they are not a religion as religion in the average Humanists worldview plays the role of Satan in Christian theology.
Let's take Richard Dawkins as the model Secular Humanist, which of the things I mentioned don't apply to him?
Well, I suppose it is up to the peanut gallery to decide. All I can say is that we first start with similarities to develop our overarching category, and then it would be differences in construct and social roles upon which one might create subcategories. To avoid the process altogether would seem to isolate us in our own culture and religious beliefs. Kind of a don’t ask, don’t tell scenario or an ostrich with its head in the sand.
That seems a strange way to look at it. Unless we can use the word 'religion' then there is no point in looking at historical belief systems?
We just acknowledge that studying historical belief systems is facilitated by not making people think in terms of a word that has inescapable modern, Western connotations that don't map on well to pre-modern, non-Western times.
The main reason many atheists want there to be a clear category of religion is because they want to feel superior by not belonging to it. It's not about understanding the past, but differentiating themselves from it.
