Anyone can see that Western civilisation is on the way out. Let me rephrase that. Anyone should be able to see that Western civilisation is on the way out, but most people don't because they are too wedded to their own paltry pleasures or selfish resentments or greedy desires or shallow ambitions. The list continues but it basically encompasses all those who do not place the good, the beautiful and the true above their own egos, and that is the majority. If ever a civilisation deserved to collapse, it is ours because we are not worthy of those who established that civilisation. We, who place the temporal above the eternal, put ourselves at the mercy of the temporal and our time has passed.
There is a solution but we will never take it. The solution is to return to tradition and the soul of Christianity. That would include a form of what is now dismissed as patriarchy since, by and large, it is only men who are willing to fight for truth and to preserve it in the face of the inevitable attacks on it, inevitable because Satan exists and wages an ongoing war against creation. This has become so apparent in our day, and especially over the last 25 years, that anyone who wishes to tread the spiritual path has to see that path in terms of the war of good and evil. If you refuse to recognise that and retreat to an 'everything is one' position you are simply being spiritually blind, not to mention irresponsible. The mask is almost completely off now and the face of evil beginning to be seen for what it is.
Satan has weakened the West with, among many other things, the debasement of culture, mass immigration and feminism. In a society that wished to preserve itself immigrants would not be given a say in how the country was run (in other words, a vote) for at least 2 generations, and their number would be restricted. The number of immigrants that flood (the word is fair) into Western countries now will inevitably change them utterly. This may have good or bad results in the long term (I'm being diplomatic), but clearly for the host nation to permit it is borderline insanity because it will destroy itself thereby. A basic instinct is self-preservation. To go against this instinct is to succumb to the unnatural and the anti-spiritual. The failure to reproduce and the desire to kill yourself are ungodly.
Feminism is the devil's secret weapon because, while ostensibly based on reason and justice, it actually seeks to reverse natural hierarchies and turn the two sexes, meant to be complementary, into rivals on the same ground. The promotion of women to previously male spheres damages society because establishing harmony and consensus becomes more important than the search for truth and excellence. This again is one of those things that its so obvious it shouldn't need saying but the ideologically committed will never acknowledge it. That having been said, feminism is not the cause of the collapse but a symptom of it though it does hurry it along as well.
I say the remedy would be a return to some sort of modified patriarchy, meaning one that takes into account the evolution of consciousness and agency of both men and women, but I am not recommending this even if it were possible which it isn't as things stand. The West must die and that is right and proper. The energies that sustained it are now weak and feeble and it has come to the end of its life. It is becoming a corpse on which the parasites will feed as it dies. But in the greater scheme of things that is not a problem because everything in this world only exists to serve spiritual needs. As the West collapses there are great spiritual opportunities for those who know how to take advantage of them. We may lament the collapse because of past good but everything dies and the West has rejected God so become evil. There is no more to be said. It must go but since the primary function of this world is as a school for consciousness and sphere in which the soul may choose or reject God and be tested thereby that is no great loss. All that is good and true and right exists in the higher worlds eternally.
