Nothing can be done. It's too late. White "men" have spent half a century scapegoating and vilifying women and mothers. Now you're dying out because women hate you and are going asexual, gay or screwing non-white men.
You get what you deserve...
We must physically remove these people.
Quite literally our elites hate us. We must form power blocks ourselves and whether there be collapse or not, stand against the sort of sordid creature who only say things like this because they never cared about our well being to begin with.
I think for many people who say they would like to "save the West", the West is something different than what it has been since say the Treaty of Westphalia of 1648. For me the West mainly represents liberalism, the scientific method, democracy and human rights. Indeed the "globohomo" many who think the West needs saving oppose.
However there is also the ethnos. I have grown up here in my home country in Europe seeing it get inundated by foreigners with skin colours different from mine. Is that something we need to save the West from? I am not quite sure. It is a conflict between ethnos and polis.
Most Americans or Brits properly informed would have sided with the Germans. As larpy as it sounds, the Reich had a viable way forward for The West. Hitler was not fighting for Germany alone. He knew he couldn't form the power block he needed without smashing some uncooperative, parasite addled heads, but he never intended to go to war with England or the United States. His purpose was to form a block with which he could maintain European sovereignty and oppose the emerging blatantly anti-Western force of international finance which armed itself with the shape-shifting ideological hammer of parasitism (bolshevism, communism, capitalism, liberalism, democracy); a subversion of The West which continues to this day.
Hitler was right, and he truly believed in what he put forward; he and his men were the greatest heroes of our era, and their defeat it's greatest tragedy. They are uniquely vilified for this reason alone.
Point being, the fundamental problem has not changed since then. Given that, the solution, by whoever's hand it is delivered, is one which will necessarily reflects theirs, albeit adapted to the times. That is to say, The West has a way forward, and a part of it begun down it but faltered against the sheer weight of the rest weaponized against it. As dimly as it is lit, that path remains yet open, for those willing to see it.
Practically speaking, any effort begins by joining, in person, with others working to kindle this spirit. First ensure you're a person worth having around, then literally move to where they are. What's next depends on circumstance, but the more people who can organize in a contiguous place the more can be done. Rely on each other over outsiders, and grow your numbers thoughtfully. Ignore naysayers as by their apathy they show they are not of the west to begin with, or are a part of it which should be lost. These organized groups having started their own institutions, communities, and centers of human action will serve to arm the broader sphere as its ideas evolve and resolve to take physical form.
