My view:
We basically have two kinds of religions. We have religions that rely heavily on theory (philosophy, ideology, theology). For instance in Abrahamic religions everything begins and ends with beliefs. You must believe in their God as the only one. Behavior is ruled in prescribed ways and judged by morals in the book. Follow the book, obey the written laws and you are "good". Disobey them and you are "bad", reject hem and you are "evil".
We also have religious traditions that rely heavily on ethical conduct. Ethical conduct does not rely on following written law, but is based on upholding mostly universal values. The most important value is not hurting other beings unnecessarily. In these religions people are free in their ideas, beliefs, but they must abide by the traditions that are translations of values a people want to uphold.
In the Far East this is called "dharmic" religions.
Nature Religions are dharmic religions.
For instance when the Pagan Meccans threw Mohamed out of town after years of fruitless proselytizing (Only his wife and a handful of direct family members followed him), it was not because he spread the idea of one God (They could not care less about what and how many Gods someone choses to worship), but because he attacked the ancestral traditions. For instance no Pagan will accept that he is forced to revere ancestors of a foreign people in stead of his own, or is forced to change his own community for some sect like community.
When Christians went to Mexico and gave statues of Jesus and Mary to the Aztecs, the Aztecs thanked them and gave the statues a place in their temple with the other Gods. If these foreigners say they are powerful Gods, lets add them to the collection and please them, no problem. When the Franciscans found this out, they went on a murdering frenzy, because for them it was sacrilege. There is deep divide between the two kind of religions, that is not ideas, but mindset.
Paganism is about upholding traditions of the ancestors. It is about communities of people that share the same tradition, often blood ties, but it can also be cultural ties based on language. It is about small local communities.
There has been done research about what makes people happiest. It turns out that people living in small communities in rural settings are happiest. That is how evolution taught us to live for millions of years and living with people we share a lot of things with makes us the happiest. All these fancy philosophies are nice thoughts, but do not really contribute to happiness.
People from the same cultural background understand each other better and appreciate each other better. They feel closer and closer bonds make people feel more secure, more at home, more grounded, and happier.
The philosophical religions are really mass religions. Because they are idea (book) based they can be spread all over the world, just like science theory. Many people today understand religion as ideas some prophet spread. What they call "the truth". For Pagans truth is a personal affair.
Abrahamists can live Dharmic as well. In fact most of "the flock" in local communities try to live their lives in a social way in their community, without even being aware what is in the book. Religion for them is just a denominator that more or less replaced their original allegiance to their ancestors. This new allegiance can be so strong that people from the same family but with different allegiance will fight each other, or avoid each others company. For a Pagan that is absurd.
Pagan religion is "the old way". Abrahamic religion is what replaced it when urban mass society came up. Now in the West Abrahamic religion is again replaced as people find new allegiance more based on individual traits, habits, interests. But many also feel lost in modern mass society. A human being needs a sense of belonging, and Pagans rather than some artificial construct want nature based belonging, like connection to the land, to the ancestors, to the people, to the culture.
If you still have a real close family you are blessed. A family that loves you, that takes care of you, that regularly meets and socializes. But this kind of thing is weathering away in modern society. In many American households people no longer eat together and live separate lives under the same roof. Parents are called upon to have a few hours "quality time" with their kids every month. No wonder social contacts are getting more superficial (social sites).
No, Paganism is no "weltanschauung". Nowadays it is mostly like-minded people seeking allegiance in shared traditions. Trying to revive some of that old feeling. This connection to Nature, the Land and one's People. Back to original culture away from this consumerism, ruthless market competition and media brainwashing. Looking for something that is more "real" than the idea worlds that we are made to swim in so we behave like loyal ants in the big anthill.
I think there is some reconciliation between a religion like Catholicism and Pagans because Catholicism did allow a lot of Pagan traditions to survive in some form and now Catholicism itself feels under threat from these aggressive Juda-Christian proselytizers who turned Christianity in a pseudo Jewish sect in which everthing Pagan is evil and Roman Catholicism is painted as a Pagan evil. It is true that Catholics have a more Pagan Dharmic mindset than protestants and Jews with their "sola scriptura" and legalistic mindset. Catholicism also is more about upholding values, rather than obedience to written law. I have always felt emphasis on morals easily creates ruthless people who abide by the law and see that as a Gods permission to every other evil that is not forbidden.
