I am the author of the Rational Male series of books
@Osiris your question isn't one of finding an ideal, but rather the shallow ideals of culture being baked into women making the majority of them incompatible with men's idealistic concept of love. An approximation of that ideal is impossible to achieve so long as men are ignorant of their own idealistic nature, women's nature, and women feel entitled to their own ideals of men.
@LastRevision The Wall begins in a woman's mental state. It's not a physical thing or even an age thing, although they are factors. It's an acknowledgement that she can no longer compete for the most desirable men that she used to when she was younger.
I agree that TRP vs. Black Pill / MGTOW get stupidly polarized on this, but their binary takes on the Wall stem from a want for an emotional high to see women get their comeuppance or to wallow in their sexless misery.
