Modern culture is evil. If you don't agree with this, let me save you some time and suggest that you stop reading here. This post discusses alternatives to modern culture on the assumption that you reject modern culture because it is evil. What are the alternatives to modern culture? Before discussing alternatives that I think can work, I will discuss alternatives that don't work.
Politics doesn't work. Moral people are an insignificant minority in all nations today. And never in history has a nation been made moral through politics. Politics is useful in a society formed by moral people. In such a society, politics can help implement the will of these moral people. This is how America worked before it became evil. But in an evil society, politics is just a contest for power, nothing more.
Modern Christianity doesn't work. Modern Christianity is all faith and no works, which means no morality. The main practical difference between a modern Christian and an atheist is that the modern Christian violates the third commandment while the atheist doesn't, making the atheist slightly less sinful than the modern Christian. I discussed in detail what went wrong with modern Christianity in The Rise and Fall of Christian Culture.
Modern Catholicism doesn't work. To a large degree, what went wrong with Protestantism has infected Catholicism. The current Pope is a total disaster. But Catholicism was essentially doomed by the Second Vatican Council which fully gave in to modern culture.
White nationalism doesn't work. No racial movement in history has succeeded without religious backing. White nationalists who want success should copy the most successful racial movement, namely Judaism. This means that white nationalists need to pick a religion for their movement. Until they do so, they are a hopeless bunch.
That completes the important options that don't work. Now let's consider options that work. History shows that all good cultures are supported by a good religion. How can one judge if a religion is good and strong enough to resist modern culture? One superficial way to judge that I have found to be very effective is just to ask whether men and women sit separately during religious service. Religions that have maintained this separation have shown that they are strong enough to resist modern culture
Orthodox Judaism works well if you are a racist jew. I am jewish but not racist, so Judaism doesn't work for me. For non-jewish racists, Orthodox Judaism is a model well worth copying.
Orthodox Christianity may work in some conditions. Mainstream Orthodox Christianity does not work in the West because it is too weak of a religion to withstand modern culture. This can be seen by the fact that the sexes are mixed in service. Historically, Orthodox Christianity has always partnered with a government that supports it, so this seems to be the condition in which it works. Currently, the obvious candidate is Orthodox Christianity in Russia where it has government backing. I haven't been to Russia, so I can't say for sure how well this works, but I think this is an option well worth investigating for Christians.
True Orthodox Christianity is a variant of Orthodox Christianity that looks interesting and may actually work in the West. But it is small and its future is uncertain. Here is a very good set of videos explaining the idea.
Conservative Mennonism is an excellent alternative for Christians. All of traditional Anabaptism is sound, but the conservative Mennonites seem to have found the optimal balance. They don't reject all modern technology as Old Order Anabaptists do (like the Amish), but they still do a good job keeping modern culture out. They are serious Christians, serious about following Jesus's teachings. The book Brethren Thinking written by an unconventional Old Order Anabaptist provides a highly intelligent introduction to Anabaptist thinking. The book An Introduction to Old Order and Conservative Mennonite Groups provides a good overview of the Mennonite variants. I specifically recommend the Mennonite groups classified as "Ultra-Conservatives" on page 162 of this book. You can find a Mennonite church near you using this map. If you have any more questions about Mennonites, you can ask on this Mennonite forum.
Islam is an alternative worth investigating. While Islam has issues today, it has worked well in the past. And it still at least upholds basic moral traditions. I believe that Islam is the religion that is most likely to have a reformation and become the next successful culture. But to judge Islam for yourself, you should visit your local mosque and read the Quran.
Mikraite is the alternative that I have chosen. None of the above options work for me because I am not a jewish racist and not Christian. So I worked with some like-minded people to form a moral religion based on the Old Testament. You can read more in What is a Mikraite?.
